The 24-year-old Italy international is in contention to make his debut for Liverpool in Sunday's Barclays Premier League game at Tottenham following his move from AC Milan.
Rodgers said: "Mario is fine. He has settled in very well and has looked fantastic in training.
"He is a good lad. The focus is very much on his football and he has done very well.
"He is moving to Merseyside. He is engrossing himself into the club and the people, but more importantly into his football. I look forward to seeing that development over the coming years."
Rodgers was, however, keen to stress that no individual is a bigger star than the team at Anfield.
He added: "This is not the Mario Balotelli show. He is a good player, a talented player. But he has got a lot of work to do here.
“We have a number of top-class players and the star of this team will always be the team."
