The January transfer window will make or break West Ham’s season.

With so many key players out injured, West Ham must invest wisely and ensure that their star players remain at the club.

That is why some of the latest transfer rumours will worry Hammers fans.

According to the Daily Mail, Paris Saint-Germain are lining up a big money move for West Ham defender Issa Diop in the January transfer window.

Diop only joined West Ham this summer in a £22m deal after leaving Ligue 1 side Toulouse.

But his immense performances in claret and blue have caught the attention of one of Europe’s heavyweights.

PSG are ready to bid up to £50m for the 21-year-old, offering West Ham more than double his summer price.

The Ligue 1 champions have been long-term admirers of the dominant centre-half but missed out to West Ham this summer.

Now they are set to test the Irons’ resolve with a big money bid.

Diop at West Ham

Diop has taken to life at West Ham extremely well. He has formed a solid partnership at the back with Fabian Balbuena.

 

Despite being so young, the France under-21 international has looked composed, mature and up to the physical challenge.

With aerial dominance, tough tackling and the willingness to put his body on the line, Diop has been a rock at the back.

And it seems like the youngster is only going to get better as he improves with each match he plays.

Why West Ham must keep Diop

If PSG firm up their interest and offer £50m for Diop, West Ham will surely be tempted.

It is a chance to make a major profit on the young Frenchman, who only signed this summer.

But West Ham must resist this and do all in their power to prevent this deal going ahead.

Diop has so much potential and his presence at the back has been crucial for West Ham this season.

As the campaign goes on, he will only get better and further establish himself as a key player in this side.

Keeping him beyond this January means that West Ham will either be able to sell him for more than £50m in the future or, preferably, he will go on to become a club legend.
