Nottingham Forest have also shown interest in Magassa
Potter wants him to be the first of two midfield signings
West Ham are in advanced talks over a deal to sign the Monaco midfielder Soungoutou Magassa for €17m (£14.7m) plus €3m in add-ons.
Graham Potter, who is under growing pressure after opening the campaign with heavy defeats by Sunderland and Chelsea, is desperate for midfield reinforcements and has been pushing for the 21-year-old to join. West Ham have had an agreement on a fee with Monaco since the weekend but have been working on personal terms.
Potter and his recruitment chief, Kyle Macaulay, have spoken to Magassa about where he would fit in. Talks ramped up late on Monday night and continued on Tuesday morning. Nottingham Forest have also shown interest in the France Under-21 international.
