Werder Bremen star Diego is aware of interest from Inter Milan.
The Brazil international midfielder is seen by Inter as a potential replacement for veteran Luis Figo next season.
Diego said: "I know Real Madrid are interested, they're one of the best teams in the world and I'd prefer to play in the Santiago Bernabeu than the Nou Camp and Barcelona.
"I have also heard about Inter Milan, but for now I am focused on Werder Bremen, where I am contracted until 2011."
