Trio extend Milan deals
The highly-rated Brazil defender has been strongly linked with a move away from I Rossoneri, after attracting interest from a number of top European clubs.
However, Milan have secured Silva's services until June 2016, the club has confirmed.
Van Bommel, who joined the Italian giants from Bayern Munich in January, has agreed a one-year contract extension with his previous deal expiring this summer.
Former Monaco goalkeeper Roma, who was also set to become a free agent next month, has signed a contract with Milan until June 2012.
