The 22-year-old is expected to undergo a medical and agree personal terms with Milan before completing a £19m move to the Rossoneri.
Balotelli has only scored once in 14 Premier League appearances this term, but Robinho is confident the Italy international can aid Milan’s bid to finish in the top three.
“Balotelli is a great player and will definitely help the squad. We are happy he has arrived and we are all going to welcome him. Let’s hope he does well for Milan,” Robinho said.
Balotelli will be suspended for Milan’s tie against Barcelona in the Champions League last 16, with the Italian side looking to avenge last season’s quarter-final loss to Barça.
After a difficult start to the campaign, Massimiliano Allegri’s side have improved in recent months and are just six points behind third-place Lazio, who occupy the final Champions League spot.
“There’s enthusiasm in the changing room and we’re getting better,” Robinho added.
“There are still plenty of games to go and every three points will help us move up the table.
“The beginning of the campaign wasn’t good, and once more the Italian league is proving to be difficult.
“But at the moment we’re experiencing a good run of form in this crucial point of the season, and with 16 games to go anything is possible.”
