AC Milan [ Images ] have failed to agree a transfer fee with Barcelona [ Images ] for Ronaldinho [ Images ] after a preliminary discussion, the Serie A club's chief executive said on Sunday.

"Yesterday we had a conference call. The figures haven't fallen into place," Adriano Galliani told Sky after Milan's 5-1 win over Reggina. "Maybe Ronaldinho won't come and a main striker arrives."

Ronaldinho's brother and agent Robert De Assis has agreed personal terms with Milan but Inter Milan [ Images ] and Manchester City [ Images ] are also interested in the Brazil [ Images ] playmaker.

Milan want a frontman since Brazilian striker Ronaldo [ Images ] is out for a lengthy spell with a knee injury and Filippo Inzaghi is now 34 years old. They have consistently said they would welcome back former striker Andriy Shevchenko from Chelsea [ Images ].

Milan are fifth in Serie A and could miss out on next season's Champions League [ Images ], which the Rossoneri won last term.

Asked if a deal for Ronaldinho might stall because of this, Galliani added: "Ronaldinho went to Barcelona when they were in the UEFA [ Images ] Cup. It happens to all the great European clubs, I hope it doesn't happen to Milan.

"Anyway, Ronaldinho is a Barcelona player, not a Milan player."
