West Ham will allegedly need to sell before they can buy in January.
Last week, West Ham United co-chairman David Sullivan told the Daily Mirror that West Ham would have to sell in order to buy come January.
"We are now at the maximum wages we are allowed to pay under Premier League rules, and therefore if we wanted to buy again in January we would no doubt have to sell someone before we would be allowed to make any new signings," said Sullivan.
The Hammers are not only set for their move to the Olympic Stadium next summer, but also spent heavily over the summer in order to sign new players.
The arrivals of Darren Randolph, Angelo Ogbonna, Pedro Obiang, Dimitri Payet, Michail Antonio and Nikica Jelavic took chunks out of the West Ham budget, whilst the loan signings of Carl Jenkinson, Alex Song, Manuel Lanzini and Victor Moses haven't come cheap either.
Now with Sullivan's admission, clubs may be looking to cherry-pick a Hammers side who defied the odds on Saturday to beat Manchester City 2-1 - and here are three players that West Ham could risk losing should Bilic want more signings in January...
Reports from The Sun on Sunday suggested that Manchester United manager Louis van Gaal was interested in a move to sign left back Cresswell following an injury to Luke Shaw. The 25-year-old defender has starred for West Ham ever since his move from Ipswich in 2014, and losing him would be a big blow to Bilic, given that the English man offers a real attacking threat from left back, providing quality from crosses and set pieces.
It would certainly be a surprise to see Payet leave Upton Park just months after arriving from Marseille, but his exceptional displays so far will no doubt have attracted admiring glances. The French playmaker's creativity and eye for goal in attacking midfield have been key to West Ham's bright start to the season, and having previously played in the Champions League, the 28-year-old could certainly play in Europe's top competition again.
Senegal international Sakho impressed for West ham last season with 12 goals in 26 games, and he has now continued those exploits this season, hitting four goals in eight games in all competitions. A dangerous, physical presence with pace and strength, Sakho may well be on the radar of other Premier League clubs - especially with the dearth of great strikers right now. As West Ham's leading striker, it's imperative that they keep Sakho at Upton Park; but if a huge offer comes in that helps balance the books, they may well risk losing him.
