The 24-year-old has played just five games across all competitions for the Hammers this term, with his last appearance coming against Crystal Palace in the middle of December.
Angelo Ogbonna, Fabian Balbuena and Craig Dawson are all ahead of him in the pecking order, and he is struggling to get back into the team right now.
Diop joined West Ham from Ligue 1 outfit Toulouse in the summer of 2018 for around £22 million, and his form over the last two seasons attracted interest from the likes of Tottenham Hotspur.
Diop reportedly told the club that he wanted to leave during the summer transfer window, with Tottenham tipped as favourites to land his services.
The North Londoners were linked with a move for the West Ham man in January, but whether they are still keen on him remains to be seen following the signing of Joe Rodon last summer.
Spurs boss Jose Mourinho dubbed Diop a monster while he was still Manchester United manager after he put in an incredible performance against the Red Devils, praising the scout that helped West Ham sign him and he is a huge fan.
Diop could still have a future at West Ham, but leaving on loan this month to play regularly and prove himself again could be his best chance of returning to the team’s starting XI.
