William Gallas has told Arsene Wenger he was wrong to let him leave Arsenal last summer.
Gallas, 33, made the short move to Tottenham on a free transfer after failing to agree terms to remain at the Emirates Stadium. While he earned positive reviews for his performances at Spurs, the Gunners' quest for silverware again ended fruitlessly, with defensive errors often to blame.
Reflecting on his departure, Gallas said: "They decided to not make the effort to keep me. It is a choice I respect, and they respected the fact I didn't want the wages they proposed. Did Wenger make a mistake in not keeping me? He made a choice, but indeed I believe he made a mistake."
He added: "In the street, Arsenal fans asked me why I left. The coach thought I was a finished player. I proved he was wrong."
The former France international went on to suggest that the same problems he diagnosed during his time at Arsenal have yet to be remedied.
"When I was captain I wanted to give a message, but they didn't get it. I may have been clumsy, but the substance was right. I came from Chelsea, where I won titles, and I wanted to share my experience, because I thought we missed commitment in our work.
"My message has not been understood and I am also responsible for that. Unfortunately the last season showed that team still misses something."
