Last season he clashed with players like Craig Bellamy and Carlos Tevez over his training methods, and other big names like Emmanuel Adebayor, Craig Bellamy, Stephen Ireland and Shaun Wright-Phillips saw a slump in form.
He said: "It's important that we all work in the same way. I hope that all players I bring in will change our way of playing.
"I want to bring in a winning mentality. You can only win a trophy when you work hard - and when you think. Because if you work and don't think, it's impossible when you play the game to do a good job.
"When I arrived at Inter they hadn't won a trophy for 15 years. In one year we changed our mentality.
"We became a strong team. We played at home and away with the same mentality.
"So, in one year you can change. But if you don't think in a technical way it will be difficult. I think our mentality must be intense.
"It must be to try and win every game home and away, and to try to win the league.
"I'm not afraid of the pressure. I played for 20 years and I have been manager for 10 years. The time of feeling pressure was in the past for me. I don't have pressure."
