West Ham United boss Sam Allardyce retains hope of signing Blackburn Rovers wing-back Martin Olsson.

Allardyce confirmed that he is chasing the Swede.

Allardyce admitted: "We have made an enquiry... negotiations are ongoing at the moment.

"In terms of what we're doing at the moment, we're as active as everybody else.

"If there's a player out there that we think can improve our squad, we'll try and move on him."
