Jason Roberts will leave Blackburn Rovers if the right offer comes along according to manager Sam Allardyce. Roberts has been linked with clubs all over the summer but nothing so far has happened. But now with Sam confident he can improve the side very shortly, is willing to let Roberts go. Rovers have the chance to let Roberts go after landing Mame Biram Diouf from Manchester United on a season long loan. Sam told the Lancashire Telegraph: "I think everyone knows by now we would listen to an offer for Jason. I felt leaving him behind rather than playing him and risking an injury would be the best bet this weekend."
