West Ham United co-chairman David Sullivan has revealed that the club could lost as much as £17million over the next 12 months.

The Hammers are due to move from Upton Park into the London Olympic Stadium next summer which is the major reason for the East Londoners spending big in the recent transfer window.

West Ham, under new boss Slaven Bilic, outlaid more than £40m on players which has basically topped up their squad for the next year or so.

Sullivan said of the situation: "As a result, 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.

"It also means we expect the club to make a loss of between £10m and £17m this year, depending on where we finish in the League and the number of games we have televised. This is indicative of just how seriously we took this window and the signings we wanted to make."
