West Ham United manager Sam Allardyce has admitted he has no idea when club record signing Andy Carroll will be back in action.
The Hammers paid £15m to sign Carroll from Liverpool this summer after a successful loan spell at Upton Park last season; however, the England international is yet to make an appearance this campaign.
Carroll suffered a recurrence of a heel injury on the last day of last season and has been out of action ever since, with his manager Allardyce unsure of when he will return.
He told reporters: "We try and get a date from the guys in Amsterdam and they are reluctant to give us any clear indication of just how long it is going to be before he can join us back here and begin training with the players towards getting into the team and playing some games.
"It is obviously a great worry and concern for us all and one we have not expected, but it is one we must make sure we deal with.
"Like I said to take the pressure of us all, we need results and we need to start achieving results that we have not achieved in the first 11 games."
West Ham will be hoping Carroll's return to action comes sooner rather than later as the club have been playing without a striker in recent fixtures.
Ravel Morrison leads the club's goalscoring charts with five goals and Ricardo Vaz Te has one less, but none of their other players have managed more than one so far.
Their players will need to be on form in front of goal to secure a result this weekend however, as they face a tough home fixture against London rivals Chelsea.
