With concerns growing over the long-term future of star West Ham centre back Winston Reid, the Hammers have recently been linked with a host of possible replacements.
The New Zealand international has just months left to run on his current contract, and the likes of Arsenal, Liverpool and Manchester United have all been linked with a move to sign the 26-year-old.
As a result, West Ham reportedly sent scouts to watch Austria centre back pairing Aleksandar Dragovic and Martin Hinteregger, whilst someone closer to home was believed to be a target for manager Sam Allardyce.
Fulham's towering centre back Dan Burn, who stands at 6ft 7in, has established himself as a key member of the Fulham defence in the past 12 months, benefiting from loan spells with Yeovil Town and Birmingham City.
A £350,000 signing from Darlington back in 2011, Burn has recently been linked with a £4m move to Upton Park as West Ham smell a bargain, with Burn's contract - like Reid's - set to expire in 2015.
However, Fulham boss Kit Symons revealed that they have a 12-month option on Burn's contract, which usually means they can extend the deal without negotiations - and no doubt putting Fulham in a better position to demand a higher fee for his services.
"We want to keep all our better players in the building," said Symons. "Dan has done well for us and is very much in our thoughts."
"We’ve got the option [on his contract] and it’s something I would imagine we would be looking to take up," he added.
If Fulham do manage to extend Burn's contract, West Ham may have to look elsewhere, with Fulham likely to demand a high fee for the 22-year-old man mountain.
