West Ham United have managed to keep star midfielder Alex Song in the country after Cameroon chose not to call him up for the African Cup of Nations later this month, but it's believed that manager Sam Allardyce is still interested in a number of midfielders.
The likes of Javi Fuego (Valencia), Pedro Obiang (Sampdoria) and Atiba Hutchinson (Besiktas) have all been touted as possible targets for the Hammers as Allardyce looks to secure a top eight finish this season.
Yet one of the more interesting bits of speculation came this weekend, with eagle-eyed fans spotting Jonjo Shelvey's car outside Upton Park!
The Swansea midfielder spent two years in the West Ham academy between 2002 and 2004, and is allegedly a West Ham fan - but that doesn't really explain why he was at Upton Park.
The 22-year-old has been linked with a move to Crystal Palace recently, with reports suggesting that the Romford-born playmaker is interested in a move back to London.
That would certainly appeal to West Ham, but Jack Sullivan - son of West Ham co-chairman David Sullivan - took to Twitter to dispel the rumour...kind of.
Jonjo Shelveys is not signing for west ham, despite photos of his car being outside Upton park— Jack Sullivan (@jsullivanwhu) January 4, 2015
Sullivan's tweet seems to confirm that the car in question is indeed Shelvey's, but that he wasn't there for transfer talks.
Understandably, this has led to West Ham fans wondering what on earth is going on. With fans talking about the sighting on Twitter, it's conceivable that Sullivan senior would try to dampen the speculation in case a rival club tried to sign him too.
For now, we have to assume that Sullivan was indeed telling the truth, but this is one to keep an eye on, with no real explanation for why Shelvey's car would be outside Upton Park.
