West Ham's great start to the season is largely down to some of the signings made by manager Sam Allardyce over the summer, with Aaron Cresswell, Diafra Sakho and Enner Valencia all impressing.
Yet one of the most outstanding players for the Hammers this term has been midfielder Alex Song, who joined the club on a season-long loan from Barcelona.
The Cameroon international, who made his name with Arsenal, made the surprise switch to Upton Park despite links with bigger clubs, with Barcelona desperate to get him off the wage bill.
His superb displays for West Ham - particularly against Manchester City when he dominated the midfield - have led to rumours of a permanent deal at West Ham.
However, their hopes of landing an ambitious full-time deal for Song have taken something of a hit after reports suggest that Liverpool and Manchester City joined the race for his signature.
Liverpool may seek to add another defensive midfielder with Steven Gerrard struggling at the age of 34, whilst City have struggled to protect the back four due to the poor form of Fernandinho and Fernando this term.
Losing out on the permanent addition of Song would be a big blow for West Ham, but links to Sampdoria star Pedro Obiang may suggest that Allardyce has already planned for the possibility of Song's exit.
Song is clearly surplus to requirements at the Camp Nou, but his form for West Ham could spark a bidding war next summer, with more and more clubs interested in signing him.
