Arsenal full-back Bacary Sagna has admitted he "is not happy with himself" after conceding he has allowed his standards to drop since making a return from a long-term injury.
Sagna, who was heavily linked with a move away from Arsenal last summer, has lacked the consistency he was noted for since arriving at the north London club from Auxerre in 2007, and he accepts he has not reached the levels of performance he was producing prior to his injury problems.
"I've not been at my best, I am going to be honest, so I am not very happy with myself," the Frenchman is quoted as saying in he Sun.
"This is a part where I need to get better and work more on my form. It has been a long time I've been working on my game as I didn't really have a pre-season. I need to breathe a bit but, at a high level, you don't have time to breathe because you have a game every few days and you have to keep going. I am looking forward to coming back to my best.
"If you don't focus 100% on the pitch, you miss something to push forward. You need somebody else to defend even better. When you are not at your best at this level, you feel it straight away on the pitch.
"You need a bit of everything to turn it around. When you don't perform as you used to, when you have been injured for so long, you need your confidence back and I was a bit low recently. I am a professional so I know this can happen, but not for too long because everyone is waiting for me to perform well."
Sagna impressed when employed in a central defensive role by boss Arsene Wenger in the 1-0 win at Sunderland last Saturday, but he is likely to switch to his more familiar full-back berth if skipper Thomas Vermaelen returns for the FA Cup fifth round tie against Blackburn this weekend.
