He is adamant Wenger remains the man to lead the Gunners back to glory.
Pires told talkSPORT: “Arsenal goes with Wenger like Wenger goes with Arsenal - you can’t have one without the other. That said, the results this season have simply not been good enough.
“But you can’t forget Arsenal have high expectations because of Arsene Wenger. He has done such a good job over all these years. You cannot forget what he has done for the club and neither should the chairman.
“It’s unfair to compare what we did between 2000 and 2006 - we had a great team, a great mix of English, Spanish, Brazilian and French players. But now a lot has changed. The club’s philosophy seems different.
“Wenger’s strategy has changed, he wants to play with a young team but you can’t win things like that, it’s very difficult.
“[Sir Alex] Ferguson seems to have found the right balance between the mix of ‘old’ and experienced players alongside the young ones and I think that’s what’s missing right now at Arsenal.
“Arsenal’s problems are a result of this policy. The team lacks balance and for the new players who have arrived, such as Santi Cazorla and Lukas Podolski, this puts them under a lot of pressure.”
