Tottenham defender William Gallas believes Arsene Wenger made a mistake in letting him leave Arsenal.
Gallas departed Emirates Stadium for bitter rivals Spurs last summer after failing to agree a new contract with the Gunners.
The 33-year-old also demonstrated that, 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 teammates, he said: "When I was captain I wanted to give a message, but they didn't get it.
