Inter have been locked in talks for some weeks with Barca for Eto'o and were favouring a cash-plus-players swap option. Hernan Crespo, Adriano and Dejan Stankovic have all been offered to the fallen Spanish giants.
Gazzetta dello Sport says Milan have since made contact with Barca with an offer of £22 million cash.
For their part, Barca management have accepted Eto'o will leave this summer for Italy.
