Writing on Twitter, reliable West Ham United inside source ExWHUemployee has dropped an enticing three-word hint over a potential move for free agent Diego Costa in January - coming as the club could look to commence their search for a 'perfect' striker who can provide strength in depth. 

Indeed, due to consistent fitness issues for Michail Antonio, and the topsy-turvy form of club-record signing Sebastien Haller, numerous reports have claimed that the Hammers are targeting a forward in January.

ExWHUemployee drops Costa hint

Of all the names being linked, West Ham reportedly have their eyes on Olivier Giroud, Abdallah Sima, Moussa Dembele and Joshua King - but now a fresh name could enter the mix.

Costa, who has recently agreed to terminate his contract with Atletico Madrid by mutual consent, could potentially move to the Irons in January as he emerges as a realistic signing for GSB and the club.

ExWHUemployee, writing on social media, has dropped an enticing three-word hint as he believes the move is possible - going on to say 'Wouldn't surprise me'.

Transfer Tavern take

The Spaniard, proven at Premier League level with Chelsea, could potentially make a move to the London Stadium and is free to negotiate with any club following his new status as a free agent.

He also wouldn't command a fee, however, it remains to be seen whether the target man would be willing to take a huge cut on his most recent £270,000-per-week wages with Atletico.

Described as a 'beast', given he is free to negotiate a potential Premier League return, West Ham could very well land him in January - and reliable insider ExWHUemployee believes the move is a realistic one.
