Kostas Mitroglou: Wanted by West Ham and Fulham

Fulham reportedly agreed a fee with Olympiakos for the 25-year-old, but their London rivals are attempting to hijack the move.

The Hammers have been the busiest side in the January transfer window, bringing in six players, and the signing of Mitroglou would be a major boost to their Premier League survival hopes.

The Greece international has been in scintillating form for Olympiakos this season, scoring 17 goals in 19 games.

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

However, they now appear to be locked in a tense Deadline Day battle with West Ham for Mitroglou's signature.
