Reports suggest City are ready to break the bank in order to sign the AC Milan star.
“He is a great player and a great person,” Robinho said in an interview with Abu Dhabi newspaper The National.
“Kaká is fantastic and has so much ability. He is strong, intelligent and fast. I hope I can play with him here. If Kaká or any other great player wants to come here, the door is open.
“It’s great when we have players like that mentioned with the club. We love it, and the ambition of the owners. All the players are hoping to make this club the best in the world.”
He continued: “I came to Manchester City because I see them growing and getting bigger. Can they be as big as Real Madrid? Yes, I hope so.
“I hope to play here for many years. I hope to make history at the club and become one of the great heroes of Manchester City. There is a long way to go in this championship and hopefully I can score more and better things will come.”
