Former England defender Sol Campbell has blamed Arsenal failings this season on a lack of strong personalities on the pitch.
Arsenal have not won the Premier League since 2004, and have just two FA Cup trophies since 2010.
The usual collapse of their title challenge has prompted calls from several quarters for Wenger to quit Arsenal at the end of the season.
Former Arsenal captain William Gallas says Arsene Wenger does not put the same demands on his players to win trophies as Jose Mourinho does.
"Personally, I do not think Arsene [Wenger] has to go", Henry told RMC. "It's all good buying top players, but if you aren't buying players with the right mentality, it's pointless". I think there is quality in this team.
Arsenal fans have been coming in for some heavy criticism recently, as the "Wenger Out" campaign begins to stir once again. But calling an entire fanbase "spineless" and "mentally weak" is, I'm guessing, probably not the way to engage said fanbase in that debate.

To answer the question above, I do think you can believe that Wenger's time is up at Arsenal and his style is no longer as effective as it used to be but still have the utmost respect for what he has achieved in his time at Highbury and then the Emirates. I have to respect that there are people who are in place there already.
"We can't forget what [Wenger] did for the club".
It's not clear who Koscielny was referring to, but a look at the starting line-up would suggest that the inclusions of Alex Oxlade-Chamberlain, Alex Iwobi and Theo Walcott - along with Mesut Özil and Alexis Sanchez - left Arsenal too exposed.
