Blackburn Rovers are monitoring Raul's situation at Schalke.
The Daily Mail says Blackburn's ambitious hopes of landing Raul have been boosted by a stand-off between the Spaniard and Schalke coach Ralf Rangnick.
After scoring a brilliant solo goal against Cologne on Saturday, Raul made a point of not celebrating.
It was being seen as a sign he could be on his way.
Steve Kean is interested but has a limited budget while Malaga and Russian side Anzhi have also shown interest.
