The Gunners have started the season poorly, winning just two of their eight games so far and finding themselves 11 points behind league leaders Chelsea.
Many observers felt before the season started that Arsene Wenger’s side lack a midfield enforcer and this key absentee would hinder their chances of maintaining a credible title push.
So far the general consensus has proved to be correct, as a lack of both bite and steel in the middle of the park has allowed teams to bully the Gunners and capitalise on their shortcomings.
A number of players who could fill such a role such as Adrien Rabiot, Sami Khedira and Alex Song were linked with a move to the Emirates in the summer, but Wenger instead opted to strengthen other areas side while insisting with duo Mikel Arteta and Mathieu Flamini.
When comparing the current team to that of the Invincible side, former fans favourite Pires highlighted strength as the main difference though admitted the Gunners could still be in for a good campaign.
"The current squad lacks the physical power the Invincibles team had in players like Sol Campbell, (Patrick) Vieira, Gilberto Silva and Thierry Henry," he is quoted as saying by The Mirror. "But in football, everything is possible. They have (the points gap) with Chelsea, but we can still win the league."
Pires, 40, joined the Gunners in 2006 from Marseille and went on to represent the club 189 times in all competitions over a six-year period, scoring 62 goals in the process.
He recently came out of retirement to sign for Indian outfit FC Goa in a bid to promote the launch of the new Indian Super League.
