West Ham United improve Martin Olsson offer?

West Ham United have reportedly increased their offer for Blackburn Rovers defender Martin Olsson.

The Hammers were thought to have had a £2m bid for the Swedish defender rejected earlier this month.

The Premier League side have now improved their valuation of the 24-year-old, according to Sky Sports News.

West Ham manager Sam Allardyce recently claimed that talks were "ongoing" to sign the full-back.
