Samir Nasri has lifted the lid on life behind the scenes at Manchester City last season under Roberto Mancini, saying it was his "worst" as a professional footballer.
Mancini's time in charge at the Etihad Stadium saw City claim their first Premier League title in 44 years as well as the FA Cup in 2011, but was tempered by persistent rumours of behind-the-scenes bust-ups.
Eventually the Italian was ousted after the Citizens suffered a 1-0 defeat in the FA Cup final against Wigan last season, with Manuel Pellegrini stepping into the vacant managerial hot seat.
Now Nasri has spoken out on what life was like under Mancini, who publicly criticised the French international on more than one occasion during his tenure.
"I endured my worst season since becoming a professional," he told the Sun.
“I am now quite happy at Manchester City whereas there was no way I could be last season.
“Roberto signed me and I started games but he would take me off before the end.
“We had some disagreements and I had some problems with him, as his methods are very different to Arsene Wenger’s at Arsenal.
“As a boss, Mancini was a typical Italian. He does not try to be close to his players.
“He would arrive at the training ground and not even say hello. He’d just tell you what he wanted to do.
“Wenger would go round the dressing room every day and talk with his players. You could express yourself.
“At the end of last season, Mancini tried to hurt my pride by saying I played at 50 per cent. It worked. I was good the last three matches.”
The former Arsenal man says he is much happier under Pellegrini, even if he hasn't been a regular starter this term.
"Although I am on the bench I’m always the first to come on. Being a substitute does not worry me," he revealed.
“I had a chat with Manuel and I will see what happens.
“His training sessions are truly something special. He came to see me on his first day in charge and told me he is counting on me. He said I am an important player and told me I will get games.
“I won’t get carried away but, if I perform well, the manager will pick me.
“I really want to have a great season now. I’m wound up for it like a cuckoo clock.
“We want to win everything as coming second in the league last season was painful.
“I know what I am capable of, as I did it for Marseille and Arsenal in my last season.
“But every time I was in a cocoon — I need a coach who really believes in me.
“That was the case with Wenger, he was a psychologist with me. There was affection in our relationship.”
