Stoke, Sunderland, Southampton go for want-away Blackburn winger Olsson
The Daily Mail says Stoke City, Sunderland, Southampton and West Ham have all been linked with the Sweden international, but Olsson has been frustrated by his failure to secure a move away from Ewood Park.
It has been claimed that Blackburn have so far rejected a £1.5million formal offer for the 24-year-old and instead want nearer £4m.
His agent Martin Dahlin said: "It is true that Martin has submitted a transfer request. Of course, he would not play in the Championship."
