Big Sam's reportedly not negotiating with West Ham to stay fuelling speculation he's thinking of leaving the club.
If the Irons' gaffer really is off when his contract is up on June 30, who's in the running to replace him?
- Slaven Bilic
The former Hammers midfielder is rumoured to be very interested in returning to his former club and with only a year left on his contract at Besiktas it seems he could be a strong contender to replace Allardyce.
- Michael Laudrup
The former Swansea City boss' name is a contender for the job, although West Ham are apparently also interested in current Swans boss Garry Monk.
- Rafael Benitez
Spaniard Benitez was apparently second in line for the role if David Sullivan and David Gold couldn't convince David Moyes to step into the hot seat. Following reports today that Moyes has said he won't be leaving La Liga this summer, maybe the former Liverpool manager is the strongest candidate.
- Harry Redknapp
He left QPR in February and sources have linked him to a possible return to Upton Park where he managed between 1994 and 2001. Allardyce also admitted last month he called Redknapp for contract talks.
Verdict: Outside chance
