Arsenal captain William Gallas accepts he has put in some "tired" performances this season and needs to raise his game to lead the Gunners forward.
By his own admission the 31-year-old France defender has not enjoyed the best of openings to the new campaign.
"Above all I miss consistency. One match is good, the other one is not so good. However, I am doing everything to get to my best again." he told L'Equipe.
"I can say we have not seen the Gallas from 2006 this term so far. In a few matches, I have not been so good.
"With the French team in Sweden and Austria, I was not very good at some moments.
"I would close my eyes if I would say I am strong. That would mean I don't recognise I did have a few bad performances - as recently with my club against Hull City. Maybe I feel a little tired."
Gallas added: "Do I experience the most difficult period since I joined Arsenal? We could say yes."
