Avram Grant says he can bring success to Chelsea - just as Arrigo Sacchi achieved at AC Milan.
"You need more than quality to succeed, you need personality and to be a positive person. You check the players and they also want to see what you can do.
"I've done many things differently. I've changed the staff, the training, tactics, the players' way of behaving and many other things. Football is simpler than people think.
"The history of every big club starts with doubts. If you see Arsenal when Wenger came, United at the start under Ferguson and even the great Milan team.
"When Berlusconi decided to take Sacchi from the Second Division everyone wanted to kill him - but the history of Milan changed. Every change takes time."
