Europe's elite learned their Champions League last-16 fate on Monday as a number of very tasty ties were announced.

Favourites Paris Saint-Germain were drawn against last season's competition winners Real Madrid - the tie of the round.

While Chelsea were drawn against their age-old nemesis Barcelona. Elsewhere Manchester United, Manchester City and Liverpool were given favourable ties against Sevilla, Basel and Porto respectively.

Here's five things we cannot wait to discover following the draw.

Neymar vs Ronaldo - who will prevail?

Many football fans were probably hoping these two European titans would meet in the later stages of the competition.

But they've be drawn together in the round of 16, so expect fireworks.

The obvious sub-plot from the tie sees recent Ballon d'Or winner Cristiano Ronaldo go head to head with the world's most expensive player, Neymar.

The pair - widely considered two of the best players on the planet, and two players happy to revel in the limelight - will be gunning for superiority.

And with the narrative that Neymar could one day move to Real Madrid lingering in the background, it will be interesting to see which man prevails.

Barcelona vs Chelsea - who wins this rivalry?

Over the years Barcelona and Chelsea have taken part in some very feisty matches, which have produced some moments of magic.

For the most part the south-west London team have prevailed against the Catalan giants.

They certainly did when the two teams were drawn against each other in the 2012 semi-final, the year Chelsea won the competition for the first time in their club's history, and also the last time the two teams came face to face.

But their 2009 semi-final lives long in the memory of Chelsea fans after they were knocked out by the away goal rule thanks to a very late strike from Andres Iniesta.

The game, which was marred by many controversial refereeing decisions, descended into chaos as the final whistle blew, and you can expect a lively atmosphere when the two sides meet in this year's competition.

How far can Tottenham go?

Last season Tottenham had a Champions League campaign to forget as they failed to get out of their group, but this year they go into the last-16 having accumulated more points than any other team.

Most impressively they also beat Real Madrid to top Group H and were part of the reason Bundesliga giants Dortmund will be playing in the Europa League.

But Spurs have drawn one of the harder teams available in Juventus, who finished second in Group D just behind Barcelona.

They'll have to be at their very best if they are to prevail against last season's runners-up and match their greatest ever Champions League finish - a spot in the quarter-final.

After all Juventus, who have been eliminated in each of their last five knockout ties with English teams in Europe, will want to finally get one over a Premier League outfit.

Pep Guardiola vs Basel - time for revenge?

Back in 2008 Pep Guardiola, who was relatively new to the whole management thing, embarked upon his first Champions League campaign as Barcelona boss.

His Catalan giants were drawn Basel in Group C and well and truly thumped them 5-0 in their first match against the Swiss outfit.

Lionel Messi, Sergio Busquets, Bojan (2) and Xavi were on the scoresheet on the day as Barcelona took their opposition to the sword.

Guardiola's Manchester City team are more than capable of inflicting a similar level of punishment on Raphael Wicky's side.

But the Swiss club will be well aware of how the Spaniard embarrassed them some 10 years ago, and will be determined to offer a little more this time round.

Can Man United and Liverpool do their ties justice?

Manchester United and Liverpool fans were likely unified when they discovered that their teams had drawn Sevilla and Porto respectively.

While both clubs are good in their own right, they are kinder than some of the other names that could have been pulled out of the hat.

So what now? Two easy wins for the Premier League teams, and spots booked in the quarter-final of the competition, right?

Things are never this easy, especially in Europe - and both clubs would do well to remember this going into the game.

Liverpool were punished by complacency last time out in their 1-1 draw with Everton, while Manchester United have also shown they can be upstaged by a supposed minnow - Huddersfield proved this to be true this season.

Also, when do these ties ever follow the script?
