Robinho insists AC Milan's players want Ronaldinho to stay.
Ronie is still waiting to open new contract talks with Milan.
Robinho said: "He is a No 1. When he is 100 per cent in shape he will become a ruthless weapon in Allegri's hands.
"He can invent an assist or a decisive goal in an instant. He is 'Dinho. A No 1."
