The agent of Ruud van Nistelrooy admits he's angry with Hamburg management over his failed move to Real Madrid.
The Bundesliga club have blocked the move and want the veteran striker to help fire them up the table from their current sixth position.
"A contract extension with Hamburg can now be ruled out," his agent Rodger Linse told the Hamburger Morgenpost.
"He cannot understand it (why Hamburg did not let him go) and he has got a problem with it. It is very, very painful.
"It is sad because Hamburg have no idea what they are doing to Ruud with this decision."
