West Ham linked manager Marco Silva has a release clause in his contract with Fulham, according to the Sun.
The 46-year-old signed a new contract until 2026 with Fulham in October last year to commit his future to the club.
Silva has remained a coveted coach and he was heavily linked with a move to Saudi Arabia last year.
Several Premier League clubs, who could be looking to bring in a new manager in the near future, have also been keeping tabs on the Fulham boss.
West Ham are said to be looking at Silva as a potential replacement for David Moyes and it has been claimed his Fulham contract has a release clause.
Clubs wanting to snare Silva away from Fulham would have to trigger a £8.6m buyout clause in his contract.
The release clause has put clubs on red alert and there is now speculation over his future at Craven Cottage.
He is likely to be a candidate to replace Moyes at West Ham if the Scot leaves the east London club at the end of the season.
