Hammers boss David Moyes will surely be looking to freshen up his options in January, in an effort to build a squad capable of making a sustained push for the top ten.
It is unclear how much money will be given to the Scot, however, and he might just have to sell in order to raise funds with which to subsequently bolster his ranks.
One of the players reportedly set for the exit door is Diafra Sakho, with the Daily Mail claiming that Cardiff City are interested in signing him.
They suggest that West Ham will demand £12 million for the Senegal international, and if the east Londoners manage to pull in that sort of cash for Sakho, it will surely go down as one of the best pieces of business that the club has conducted in recent years.
The 27-year-old joined the Hammers from Metz in the summer of 2014, and despite starting off reasonably well in east London, he has played a peripheral role for the club over the past two years.
Since the start of the 2016/17 campaign, Sakho has played just 19 games, scoring four goals, and he actually admitted that he wanted to leave the London Stadium in the summer.
Moyes has plenty of other options at his disposal, including the likes of Andy Carroll, Javier Hernandez and Andre Ayew, so he surely wouldn't miss the Senegalese frontman.
And for £12 million, West Ham will feel like they have struck gold.
