Anybody can play up front, it is whether they are any good in that role. World football is not currently overflowing with world class strikers.
Oh don't get me wrong,Wenger is not blameless in this.Personally I think he should have replaced Mertesacker this time last year.And our injury record is soooooo incredibly fúcking sad,boring and downright maddening.As for better than what we have I just don't see it out there
