Okay Arsenal fans this it, the latest chance for the Gunners to take advantage of the struggles of our old enemy and get one over Manchester United. There is the small matter of a trip to Wembley for the FA cup semi-final as a prize as well.
Louis van Gaal has made just one change to his side, with Luke Shaw coming in for the banned Jonny Evans and Rojo moving from left back to the centre. So Di Maria and Fellaini keep their places and Falcao stays on the bench.
Arsene Wenger has been a lot more liberal with his team selection, making five changes to the Arsenal line up that beat QPR last week. It is no surprise to see the boss bring Danny Welbeck in, hoping to get some of that fgormer club effect from the England striker.
We already knew that Szczesny and Mertesacker were set to start, with the other two players coming in the Spanish left back Nacho Monreal and Alex Oxlade-Chamberlain in central midfield. Giroud drops to the bench so Ozil will be playing in one of the wide forward roles with Welbeck in the centre and Alexis on the other side. Cazorla moves back to his favoured CAM role.
Bellerin, Mertesacker, Koscielny, Monreal
Alezis, Chamberlain, Cazorla, Ozil
subs: Martinez, Chambers, Gibbs, Ramsey, Walcott, Akpom, Giroud
