Barcelona wanted to sell Ronaldinho to Manchester City, admits AC Milan's representative in negotiations, Enzo Bronzetti.

"This was the most difficult negotiation I have ever overseen," said the FIFA agent and expert on Spanish transfers.

He was in the decisive meetings between Milan general manager Adriano Galliani, Barcelona President Joan Laporta and agent Roberto De Assis.

"Barcelona had decided to sell Ronaldinho to Manchester City for £25m against the £15.8m offered by the Rossoneri.

"Their plan was to hand Samuel Eto'o to Milan for that sum instead. But at the end of the day, it all went well."
