Shrewsbury Town 0 West Ham 0, FA Cup: Joe Hart denies his former club to force third-round replay  

The Shrews deserve their replay at the London Stadium after an excellent performance, in which they outclassed Premier League opposition for long periods.

West Ham were frankly dire, with another 90 minutes of football their punishment for being so completely unimaginative.

Shrewsbury so, so nearly go one on one after a great break from midfield, but Nolan can't get the final ball right and Payne gives away a free kick.

West Ham finally show some enterprise going forwards, forcing Shrewsbury onto the back foot.

All they have to show for it so far is a Masuaku long throw into the box, however.

Final change for the Shrews, who are really going for it now.

Shaun Whalley is replaced by young forward Arthur Gnahoua.

Chance to win it for Shrewsbury!

A long free kick is pumped into the box and headed across goal by Aristotle Nsiala. Stefan Payne wins the ball in an unlikely position and squares to Jon Nolan, but he can only blast over the bar from close range.

Winston Reid is forced off after seemingly twisting his knee.

Domingos Quina is on, forcing a reshuffle in the West Ham defence.

It's another substitution for Shrewsbury, with Carlton Morris coming off for striker Stefan Payne.

Pedro Obiang dribbles through a couple of tackles and fires through a crowd of Shrewsbury defenders, but he drags his shot across the goalmouth and out for a goal kick.

West Ham's free kick comes to nothing after a lackadaisical delivery.

Cullen is on the sidelines changing his bloody kit and definitely missing a front tooth, though it appears he wants to play on.

West Ham have a free kick 25 yards out after Ogogo accidentally boots Cullen in the face, leaving the young midfielder with a bleeding mouth and possibly a missing tooth.

The Shrews make their first substitution of the match, Max Lowe coming on for Alex Rodman.

West Ham fans have their hearts in their mouths as Abu Ogogo makes a slaloming run into the box, eventually shooting straight at Joe Hart from a tight angle.

West Ham make a substitution, Javier Hernandez coming off for 20-year-old Spanish striker Toni Martinez.

Whalley gallops through the midfield and it looks as if Shrewsbury will go on the break, but Josh Cullen nicks the ball away belatedly.

Masuaku, seemingly the only West Ham player capable of initiating attacks at the moment, wins a corner for the Hammers.

Shrewsbury clear. Set pieces have become a war of attrition at this point.

Shrewsbury win a corner after a great chance for Whalley, with Declan Rice the only thing between the Shrews midfielder and a goal at the back post.

West Ham win a free kick for a shove in the box, temporarily easing the pressure.

Arthur Masuaku gets a good ball into the box, but Dean Henderson is there to gather before it can find anyone in claret and blue.

Sadler is back on with his head heavily bandaged.

Ten-man Shrewsbury have West Ham on the ropes, Carlton Morris and James Bolton playing a give-and-go to the right of the area before the latter smashes a vicious cross into the box.

It's scrambled away in desperation, but not before a mix up on the ball sees the Shrews squander a great shooting opportunity.

Meanwhile, Mat Sadler's head wound appears to have reopened. He's left the pitch to get stitches or staples, presumably.

West Ham squander a series of free kicks, thrown-ins and half-decent passing moves, but are struggling to create half chances at the moment, let alone chances.

Pedro Obiang finds Andre Ayew with one ball into the box, but he can only direct another weak header at Dean Henderson.

Alex Rodman runs all through the West Ham defence and across the face of the box, but attempts to set up Shaun Whalley for the shot rather than taking it himself.

The move fizzles out. It's an early warning for West Ham.

... and the body language from the West Ham players is telling. They'll have to be less lethargic to get the better of this second half.

It's indicative of West Ham's general shakiness that Shrewsbury get another chance before the end of the half, winning a corner after a mix up in defence and causing havoc in the box before the ball goes out for a goal kick.

The Shrews have been by far the better side so far and West Ham fans will surely have that sinking feeling. David Moyes needs to re-energise his flagging team at half time or the upset is on.

Jon Nolan fizzes a shot past Joe Hart's near post from the edge of the box, capping a half in which Shrewsbury have looked far likelier to score than West Ham.

Godfrey wins a free kick almost on the halfway line, this after being brought down by two or three mistimed tackles.

The delivery has 'goal at the death' written all over it, but it drifts too far wide of the danger zone.

Andre Ayew manages to get a low shot on target from a narrow angle, but there's no real venom in it and Dean Henderson collects.

Sadler launches a big free kick up for the swarming Shrews but West Ham clear.

Shrewsbury are well on top here, largely dictating the tempo of the game.

Joe Hart makes a great save first from Mat Sadler and then from Alex Rodman, as Shrewsbury suddenly up the tempo and threaten to roar into the lead.

Sadler got in behind and saw his shot across the face of goal pushed out brilliantly by Hart, while Rodman stung the West Ham keeper's palms from outside the box.

The free kick comes to Obiang, who directs a weak header on target but straight at Shrews goalkeeper Dean Henderson.

Meanwhile, Ayew and Sadler are back on.

Andre Ayew and Mat Sadler clash heads in the Shrewsbury half, leaving the former writhing on the floor and the latter bleeding from the head.

Both are forced to leave the pitch for treatment. It'll be a West Ham free kick when play resumes.

Chance for Shrewsbury!

Declan Rice clears straight to Omar Beckles on the edge of the West Ham area, before the Shrews defender shapes up and shoots just over the bar.

Referee Paul Tierney has a word with Pedro Obiang after he fouls Nolan in the middle of the park.

Whalley's in-swinging delivery is a dangerous one and Joe Hart is forced to come out and smother the ball under pressure from Godfrey.

West Ham win a free kick in Shrewsbury's final third, but Masuaku produces a fairly awful delivery which is easily cleared.

Javier Hernandez is down clutching his knee after a jarring clash with Shrews captain Abu Ogogo, who challenged him – fairly, mind – as he attempted to clear a loose ball.

After a break in play it looks like Hernandez will be able to continue, which is good.

Shrewsbury win a corner after a long free kick from Shaun Whalley causes chaos in the box.

West Ham struggle to clear their lines but eventually hack the ball away. The Shrews are giving as good as they get here.

Shrews midfielder Ben Godfrey makes a great break in the middle of the park, before Alex Rodman wins a free kick in a promising position outside the box.

Jon Nolan's shot ricochets off the wall and out to safety. Meanwhile, Joe Hart is now shielding his eyes from the bright sun with a cap requisitioned from the West Ham fans.

Cheikhou Kouyate wins a corner for West Ham after good work from Masuaku.

Carlton Morris clears at the near post but the ball is pumped back in for Kouyate, who sends a glancing header wide of the post.

It's been a scrappy opening spell which may well herald an old-school cup tie.

Arthur Masuaku has made a few inroads down the left for West Ham, but other than that neither side have made much in attack.

Can you feel that? Yes, that's the magic of the cup flowing through your veins.

... and Joe Hart prepares to lead his West Ham teammates out against his old club.

Meanwhile, in the BBC, studio, all the talk is of a shock result for Shrewsbury (to the point where it might not actually be that much of a shock).

"We hope so," Paul Hurst says when asked whether Shrewsbury can beat the Hammers. "We know we're going to have to be at our best. West Ham have put a strong team out, so I think they've given us that respect."

Though he may have ill-fated memories of facing Shrewsbury as a manager, David Moyes spent three years at the club as a player between 1987 and 1990.

Meanwhile, out-of-favour goalkeeper Joe Hart began his career with the Shrews, making 58 appearances before signing for Manchester City in 2006. He returns in unhappy circumstances, having been demoted to the West Ham bench in recent times.

Having seen fellow Premier League strugglers Stoke beaten by lower-league opposition yesterday, West Ham fans will be desperate for their side to avoid an FA Cup upset this weekend.

While Stoke succumbed to a 2-1 defeat to Coventry City at the Ricoh Arena – a result which cost manager Mark Hughes his job – West Ham travel to Shropshire today to take on Shrewsbury Town. The Shrews are currently second in League One and undefeated in eight matches, making them exactly the sort of team who could cause problems for an indifferent Premier League side.

Even more worrying for West Ham supporters, David Moyes has expressed little enthusiasm for cup football in the run up to their third-round tie. Speaking in the midweek,  he said: "We can’t afford to damage our league season. If I thought I could win the FA Cup I would definitely try, but I would have to think twice if I thought it was going to affect our results in the Premier League."

West Ham are 15th in the top flight after something of an upturn in form since Moyes' arrival, but the Hammers are hardly invulnerable to disaster. Meanwhile, Moyes has already tasted FA Cup defeat to Shrewsbury once in his managerial career, when in 2003 his nascent Everton side were beaten by the Shrews in the third round.

A repeat of that result this afternoon would be a blow to fan morale at West Ham, even if Moyes might tacitly appreciate the chance to focus on the Premier League relegation battle. With wind back in their sails after a listless last few months under Slaven Bilic, however, it would be a waste to allow that momentum to dissipate in the face of the quietly confident Shrews.

When he took over at New Meadow in October 2016, Shrewsbury manager Paul Hurst inherited a team which were rock bottom of the third division. Having escaped relegation that season after finishing in the lower-mid table – a fate which Moyes would take in a heartbeat right now – Hurst will no doubt feel that his side are capable of upsetting the odds and making national headlines.
