Robinho believes that Balotelli will improve a Rossoneri team that have revived their hopes of qualifying for the Champions League following a disastrous start.
"Balotelli is a great player and will come to help the team," said Robinho. "We are happy and the locker room awaits him with open arms.
"We hope he can have a great season here at Milan."
Balotelli, 22, has scored one goal in 14 Premier League appearances this season.
