West Ham United are reportedly monitoring Fulham defender Dan Burn and could make a £4m move for the player in the next transfer window.

Burn, who joined the Cottagers from Darlington in 2011, has impressed Sam Allardyce and the Daily Mail claims that the Premier League outfit may bid for the towering centre-back, with the long-term future of Winston Reid still unresolved.

Allardyce is said to be reluctant to lose Reid, but the Hammers may decide to consider bids with the defender thought to be unwilling to listen to offers for a new contract.

Burn may not be the only option being explored by West Ham as they sent scouts to watch Russia's Aleksandar Dragovic in action against Austria.

However, the London club could face competition for the Dynamo Kiev star's signature from Arsenal, Chelsea and Juventus.
