So, the big match is here.

Now that Arsene Wenger has announced he will leave the club at the end of the season, this Semi-Final versus Atletico Madrid in the Europa League is perhaps our biggest game of the season.

The first leg is at home at The Emirates, and we will have to keep it tight if we’re to go to the Wanda stadium in Madrid and still be in with a chance. It’s clear what we have to do against a class outfit like Diego Simeone’s side.

We need to take a winning scoreline into the second leg - preferably with a clean sheet.

Unfortunately, keeping a blank slate at the back hasn’t exactly been a strength of ours this season. In fact, it could be perceived that our defence is as weak as it has ever been.

It would be great to be able to take our strongest team into this game, but Arsene did give us clues as to who will play, when he named his side for our 4-1 win over West Ham in the weekend.

Wenger stated that he wanted to name his strongest side and gain some fluency by doing so - hence the exclusion of Pierre-emerick Aubameyang. The striker is cup-tied for the Europa League and has been a mainstay in our Premier League team, but Wenger went with Lacazette up top in order to get the Frenchman’s legs stretched and also give him a bit of extra confidence.

Danny Welbeck and Alex Iwobi started the game too, and it is almost certain that the England man will get the nod to play. In regards to Iwobi though, much will hinge on the fitness of Jack Wilshere and Mesut Ozil.

Both missed out in the win over the Hammers - Ozil through sickness and Jack through injury - and while Ozil may have a chance of playing, Jack’s chances are less so. Iwobi’s odds of getting the start are also increased by the unavailability of Henrikh Mkhitaryan, who is unable to return just yet.

Another player who misses out is Mohamed Elneny, who turned over his ankle in the weekend’s win. The Egyptian has been in fine form of late and will be sorely missed, and it means that Granit Xhaka will not have the defensive cover he normally needs to thrive. So much will hinge on Aaron Ramsey.

The Welshman is in a purple patch in front of goal and his runs into the box are so effective at either picking up a vital goal or at the very least providing a diversion for his teammates. If we are to score, Ramsey will most likely play a part.

Our defence pretty much picks itself - Hector Bellerin, Laurent Koscielny, Shkodran Mustafi and Nacho Monreal will take their places in the side, with Petr Cech probably missing out in favour of Ospina, and because of a minor injury.

Diego Simeone has maintained that Diego Costa will miss out this game through a knock, but the Brazilian-turned Spaniard is fit and raring to get revenge on Arsenal, after playing in the Chelsea side last season that lost in the FA Cup Final. Juan is out though, and it means Simeone will have to shuffle the pack.

The dangermen for Atletico will be Griezmann and Niguez. The diminutive Frenchman has the capacity to turn a game on its head, and Niguez not only runs games, but also possesses all the attributes needed for a career as one of the best. If we are to have any success, then both will have to be nullified.

The game is sold out - for real this time - and we need to bring the noise and back our boys. Let’s do this.

Predicted Lineup - Ospina, Bellerin, Koscielny, Mustafi, Monreal, Xhaka, Ramsey, Ozil, Iwobi, Welbeck, Lacazette
