West Ham have made a last-ditch bid to try hijack Kostas Mitroglou’s proposed move to Fulham, according to Sky Sports.

The Cottagers reportedly agreed a fee with Olympiakos for the highly rated forward, but now it seems their London rivals have made a bid of their own.

Sam Allardyce has been one of the busiest managers during the January transfer window, bringing in six new players to help his sides relegation battle.

The capture of Mitroglou would be considered a major boost to their survival hopes, with the Greek forward scoring 17 goals in 19 matches this season.

Fulham have been holding talks with Olympiakos throughout the week, and moved closer to sealing the deal on Wednesday after agreeing a fee, believed to be in the region of £12.5million.

However, it seems there could be further twists on deadline day, with the Hammers making a last-gasp bid to bring him to Upton Park.

Mitroglou had previously been linked with both Arsenal and Liverpool, but looked set to stay at Olympiakos after signing a new contract at the end of last year.

A Premier League switch does now look imminent, but it remains to be seen at which London club he will arrive.
