According to Daily Mail, Chelsea manager Antonio Conte's position is under fresh scrutiny following Sunday's toothless showing against West Ham.
Despite the fact Chelsea can still win the FA Cup there is growing concern at Stamford Bridge that their season will capitulate.
Conte was expected to go at the end of the season, however, the decision for him to leave could yet accelerate.
Chelsea's recent form has been poor, with last weekend's 3-1 home defeat by Tottenham Hotspur leaving them adrift of their north London rivals in the race for the top four.
That margin now stands at 10 points after Chelsea dropped points in the wake of Spurs winning 2-1 at Stoke City on Saturday.
With just six matches to play, it looks increasingly likely the Blues will be playing Europa League football next season.
They can still win the FA Cup, and face Southampton in the semi-final at Wembley on April 22, but that will come as small consolation.
They were also outclassed by Barcelona in the last-16 of the Champions League last month, losing the second leg in the Nou Camp 3-0.
On Sunday, they led West Ham courtesy of a goal from Cesar Azpilicueta 10 minutes before half-time. But they had to settle for a point after Javier Hernandez levelled.
