Gallas departed Emirates Stadium for bitter rivals Spurs last summer after failing to agree a new contract with the Gunners. And the 33-year-old demonstrated he can still cut it in the Premier League following a solid debut season at White Hart Lane. Of his decision to part company with the Gunners, Gallas told L'Equipe: "I left Arsenal because we could not agree on a financial level. "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 Arsene Wenger make a mistake in not keeping me? He made a choice, but indeed I believe he made a mistake. "In the street, Arsenal's fans asked me why I left. The coach thought I was a finished player. I proved he was wrong." Gallas endured a controversial time at Arsenal, in particular during his period as captain of the club. Reflecting on his much-publicised clashes with a number of his former Gunners team-mates, he said: "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. But unfortunately the last season showed that team still misses something. "It is too easy to say all the Arsenal problems came from William Gallas." Gallas also commented on his relationship with French compatriot Samir Nasri, the pair having fallen out after a dispute over France's Euro 2008 campaign. He stated: "Samir Nasri? People tried to show me as an ugly duckling, but the images showed the contrary. Samir Nasri knows the problem. He can't lie to himself."
