Fulham have seen an offer for Issa Diop accepted by West Ham United.
Foot Mercato says Diop is moving to Fulham for €20m.
The Frenchman will sign a five-year contract with Fulham once he completes his medical.
The 25-year-old switched from Toulouse to West Ham in 2018 for €25m.
Diop only played 12 Premier League games last season.
