- Carroll has been sidelined with a groin injury
- The Hammers striker is hoping to resume training on Friday
- Cresswell, Masuaku and Ayew will all be fit for selection
Slaven Bilic will give Andy Carroll every chance of proving his fitness for the Premier League fixture against Watford on Saturday.
Carroll has been sidelined with a groin injury and was forced to miss the last game against West Brom at London Stadium.
The West Ham United forward travelled with the first-team squad to Dubai last week and has been working hard in the gym this week as he looks to regain full fitness.
Bilic is hoping that Carroll will be able to start training again on Friday and will then make a late decision on whether to include him in the squad for the game at Vicarage Road.
“Regarding the game against Watford, he'll try to run today (Thursday) and if he's good then maybe he has a chance to be in the squad for Saturday. To be fair I don't think about Chelsea now.
“I don't want to rule him out for Watford. With Andy you never know, if he can run today and train tomorrow then maybe he will be in the squad for Saturday.
“This is not a big injury but he needs to play, he needs to be available and hopefully he will train tomorrow, whether he will be available for Saturday, that would be great but if not definitely Chelsea.
“He didn't train yesterday but he was in the gym for an hour and a half. He's a big lad, he gives everything and he is looking after himself.”
With the exception of Angelo Ogbonna who is ruled out with a knee injury and Diafra Sakho, who is working his way back to fitness after a back injury, the Hammers boss should have a full squad to choose from for the Watford game.
Aaron Cresswell has resumed training following a slight knock which forced him to come off at half-time during the 2-2 draw with West Brom.
Arthur Masuaku is also available for selection following his knee injury, while Club record signing Andre Ayew is also pushing for a first-team start after getting another two weeks of training under his belt.
