3-4-2-1: Arsenal's Strongest Possible XI vs Bournemouth

Arsenal defeated Leicester City in the opening game of the Premier League campaign but then lost to the likes of Stoke City and Liverpool.
The North Londoners are already six points behind league leaders Manchester United and must step up big time if they are to challenge for the PL title.
As far as Arsenal’s team news is concerned, Wenger opted to bench summer signings like Lacazette and Kolasinac against the Reds in their last game. We can expect the duo to return to the starting lineup to face the Cherries on Saturday.
The Bosnian wing-back should replace Oxlade-Chamberlain, who completed his deadline day to Liverpool. On the other hand, the French striker must replace Welbeck in the starting XI.
In the back line, German international Shkodran Mustafi should return to partner Monreal and Koscielny.
As far as the midfield is concerned, Coquelin should start and partner Xhaka in the center of the park for the Gunners. Here is Arsenal’s strongest possible 3-4-2-1 XI vs Bournemouth.
