Arsenal fullback Bacary Sagna believes he's already improved as a player since his arrival in the summer from Auxerre.
"That is why I give my best day by day. I play regularly, but everything can change quickly. I have to remain focused.
"My technical improvement is due to training methods at Arsenal. We do a lot of passing games and play in small zones at training.
"I think I have to continue to work in defence, sometimes I give possession away stupidly, and on the offensive aspect I have to be more decisive."
