AC Milan have failed to agree a transfer fee with Barcelona for Ronaldinho 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 and Manchester City are also interested in the Brazil playmaker.
Milan want a frontman since Brazilian striker Ronaldo 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.
Milan are fifth in Serie A and could miss out on next season's Champions League, 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 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."
