The Giallorossi are struggling financially and will need to balance the books when the transfer window reopens. With that being the case, the Guinean may well be sacrificed.
Diawara only moved from Napoli for €21m last July but injuries have limited him to just 10 league starts this season.
With Roma also lining up an expensive move for Udinese’s Rolando Mandragora, CalcioToday report the 22-year-old may not have a future at the Stadio Olimpico.
The Hammers have been linked with Diawara previously, although that was before he moved to the Giallorossi. It is believed they could face competition from the likes of Newcastle and Everton this time around.
Whether West Ham would have the money to finance a deal, it does seem questionable, especially if they don’t bring in any funds from player sales.
