Sakho has missed much of West Ham's season with injuries, which could put off potential buyers.

Sakho made only his third Premier League appearance of the season against Arsenal this month, having struggled with hamstring and back problems.
Now back fit, the Sun reports that the Senegal striker was due to be named as a substitute for the second game running at Sunderland on Saturday, only to refuse claiming injury.
That is in turn said to have prompted a 'blazing row' between Sakho and West Ham boss Slaven Bilic, with the pair having 'barely spoken' since.
It is, however, claimed that showdown talks have been scheduled for later this week, with the Hammers hoping that Sakho could return to contention for Saturday's visit of Everton.

Nevertheless, the Sun's report suggests the London Stadium club have already decided the 27-year-old's long-term future, although it adds they could struggle to find a buyer because of concerns over injuries.
West Bromwich Albion were strongly linked with a move for Sakho during last summer's transfer window, however it remains to be seen whether or not the Baggies will renew their interest in the former Metz player, who is set to enter the final year of his contract.
