Seedorf signs for another season
The Dutch midfielder's contract was due to expire this summer but he has now been kept on for one more year.
Seedorf has been with Milan since 2002 and has made more than 200 appearances for I Rossoneri.
He scored four goals in 30 Serie A appearances this season to help Milan win their first Scudetto since 2004.
The 35-year-old is the latest player to have had his contract with Milan extended, as captain Massimo Ambrosini, Thiago Silva, Mark van Bommel, Flavio Roma, Alessandro Nesta and Filippo Inzaghi all signed new deals this month.
