Gunner in tough situation

Some would say that the 2-0 win against Man. United was the best game the gunners have played under their new boss. It was consolation after the shocking trip to France where they lost even after scoring in the 3rd minute by Iwobi. They ended up losing 3-1 and this made Cech's return more painful who is set to retire after this season and is only restricted to European games now. The gunners on sunday showed their isn't any formation that their midfield can't carry out, the combination of Ozil,Ramsey and Xhaka was sublime. Lacazette was earned him a red card in the round of 32 has his suspension being reduced and is allowed to play in the 2nd leg. The formation in the midfield has to be very precise as they are without first choice defender Sokratis, who got two yellow cards in the first leg. Unai is expected to got with 3-4-1-2 but 3-4-3 also could be on the cards as Niles showed his command on the right side even though "Pogba" threat was their. Even if they manage two goals the tie is in their hands and the Emirates is gunners fortress so Zenit would have to be play much better football than they did in the reverse fixture. Zenit's attack is expected to provide a threat to the gunners as their ability to score from set pieces is set to test the defense when they are with "Sloppy Mustafi." If Zenit want this game in their bag then they need to play superior in midfield and have total command.
