The Hammers have long been linked with a move for Olsson as Allardyce knows him well from his time in charge at Ewood Park. The 24-year-old has never hidden his desire to move back to the Premier League following Rovers' relegation and the east Londoners believe a deal can be done. A figure of around £7million has been reported in the media but Allardyce dismissed that number and said:
"I don't think that's true, no.
"Negotiations are ongoing."
