Petit wrote in the Daily Mail: "After three seasons at Arsenal I joined Barcelona, but if I had the power to change the past, I would come back and change the day I said 'yes' to the move. It was bad timing for me to leave Arsenal.
"When I first went to Barcelona I realised that football is a passion, but it was more about politics. So after six months I wanted to leave the club. I hated my time over there. Honestly I hated it. I was counting the days - day after day - until I could leave."
