5) Walcott’s return could be a boost
Theo Walcott has been eased back into action after a lengthy spell out through injury, but now is surely the time for the England winger to be starting out wide again. When he came on as a substitute last night, Arsenal finally looked a little more dangerous upfront and managed to carve Monaco open a little more.
Additionally, while Danny Welbeck is also not an ideal first choice striker, it might be worth giving him a chance in his preferred position instead of continuing to play him out wide, where he has not managed to make the desired impact, and where he is certainly an inferior option to a fully fit and on-form Walcott.
