The 49-year-old is pleased with how his side performed in the 1-1 draw against AC Milan but believes it will take time for the players to adapt to his methods
Inter coach Roberto Mancini admits that he does not know how long it will take his charges to adapt to his tactics.
Walter Mazzarri was fired during the international break after leading the Nerazzurri to a poor start to the season, with the former Manchester City boss returning to his old club in his stead.
The 2010 European champions drew with local rivals AC Milan during his first game in charge on Sunday and the 49-year-old says he needs time to fix the team’s problems.
“Derbies are always difficult and this was no different,” he told Sky Sport Italia.
“I am very happy with the way the team moved, as with five days together to change a system after a year and a half playing 3-5-2 was not easy. They all did very well.
“I don’t expect to change a team completely in five days, especially when the systems are different. It will take time, but our objective is to win as many games as possible quickly, even if we’re not at 100 per cent.
“It takes a while, even though many of these players have already used a four-man defence, especially on international duty. It just takes time and I honestly don’t know how long.”
Mancini’s next game is a Europa League clash with Dnipro at San Siro.
