Olivier Giroud joins the 100 club and Nemanja Milunovic escapes red: Five things you missed from BATE Borisov 2-4 Arsenal

• e-mail

Arsenal made light work of the Europa League once again with a 4-2 victory over BATE Borisov in Belarus.

Goals from Rob Holding and Olivier Giroud and a brace from Theo Walcott secured a comfortable victory for Arsene Wenger's men.

As ever, Sportsmail were on hand to pick up anything you might have missed from the game.

New kids on the block 

Arsene Wenger said the Europa League would act as a chance to give his fringe players and youngsters more game time and he certainly meant it.

Reiss Nelson and Ainsley Maitland-Niles were given a run out in Barysaw but it was 18-year-old Joe Willock who caught the eye when the Gunners' team was announced.

The young midfielder was handed his first senior start having featured just once for the club before, in the Carabao Cup win over Doncaster.

With the side in a comfortable lead, Wenger then handed a debut to Marcus Mcguane, making the 18-year-old, who has graduated all the way from under-6s, the 847th player to represent the club. Fellow youngster Eddie Nketiah then became the 848th.

Milunovic a lucky boy

Willock will have no doubt have expected a far more physical game of football than he is used to but Bate's Nemanja Milunovic took things one step too far.

The youngster was caught in the face by a swinging elbow from the defender as he attempted to close him down during the first half.

The Serb escaped punishment, however, as the referee merely awarded a free-kick. Replays suggested there was intent and a red card would certainly have been justified.

'It’s one of them, it was a really heavy one on Willock,' BT Sport pundit Martin Keown said at the break. 'I have been really impressed with him another we don’t mention but he’s physical and strong but look at the flailing arm that caught him. 

'The referee certainly had a great view, I don’t understand why the referee isn’t booking him or even sending him off. He reacted because he knew the severity of it but he didn’t show a card.'

Giroud joins the 100 club

Olivier Giroud bagged Arsenal's fourth goal of the night and in doing so ended his seven-game wait to join an exclusive club.

The Frenchman slotted calmly from the penalty spot after Stanislaw Drahun was deemed to have pulled back Shkodran Mustafi.

The strike was the 100th of his 238-game Gunners career, making him the 12th fastest player to reach triple figures, one game faster than Robin van Persie.

He has some way to go if he wants to catch record goalscorer Thierry Henry, however, who netted 228 times for the north London outfit.

Gordeichuk doesn't hold back

Bate's players were visibly frustrated with their first half display and none more so than Mikhail Gordeichuk.

And the midfielder vented his anger when presented with a golden chance to to reduce the deficit in the 67th minute.

Mirko Ivanic's header which was parried into his path by David Ospina and the 27-year-old couldn't resist absolutely blasting the ball into the empty net from a couple of yards out.

Slightly unnecessary, but it did the job.

Reiss Nelson ruining careers 

A lot of fuss has been made about 17-year-old midfielder Reiss Nelson and the starlet showed glimpses of exactly why.

The Englishman made a very lively start to his second European outing before wowing fans with one particular moment of skill.

Nelson, faced with a defender on the wing, dummied left, right, then left again to leave his man sprawling across the floor.

Twitter, as usual, was there to make the most of it.
