“[Robinho] is a great friend and a spectacular player.” the playmaker told ESPN.
“It would be a pleasure to play with him, who knows? We live in different realities, he’s at Milan and I’m at Wolfsburg.
“We are happy, but there is still much to do. Maybe one day we will meet, it would be a pleasure.”
His career in Italy was short after an unspectacular season with Juventus in 2009/10 after joining from Werder Bremen.
