Former Arsenal striker Emmanuel Adebayor has claimed that the current squad is over-reliant on Mesut Ozil and Alexis Sanchez.
The duo's long-term futures at the Emirates Stadium are uncertain as they are yet to sign new contracts despite their present deals having just 18 months remaining.
Sanchez is the Gunners' top scorer this season with 16 goals in all competitions and he has also provided 13 assists while Ozil has scored nine goals and added seven assists.
"Arsenal have a good team but if Sanchez gets injured I don't know who they've got," Adebayor, who played for Arsene Wenger between 2006 and 2009, told The Guardian.
"If you look at Chelsea, when Eden Hazard gets injured they've got Willian; if Willian gets injured they can still play Victor Moses further forward.
"Arsenal's problem is that today they are just Ozil and Sanchez. If one of them gets injured, it is a problem."
Adebayor has been without a club since his contract with Crystal Palace expired at the end of last season.
