Issa Diop is undergoing his medical at Motspur Park ahead of his proposed £15m from West Ham to Fulham.

The 25 year-old French defender is on the cusp of becoming Marco Silva’s latest signing as the Whites seek to strengthen their defence. Diop had been disappointed that West Ham had failed to reach agreement with Fulham over a transfer earlier in the window and is believed to contest David Moyes’ assertion, made after the Hammers’ opening weekend defeat at Manchester City, that he had made himself unavailable for recent matches.

Silva had sought central defensive reinforcements all summer after the release of Alfie Mawson and Michael Hector left the Portuguese head coach with only two senior centre halves in Tosin Adarabioyo and Tim Ream. That pair played well to keep Liverpool at bay on Saturday, with loan signing from Brighton Shane Duffy introduced as a late substitute as Fulham sought to hang on to a point.
