Watford start a hugely important week in their search for Premier League promotion with a trip to rivals Luton Town.

With William Troost-Ekong, Nathaniel Chalobah and Tom Cleverley all subject to late fitness tests, there could be one or two changes.

Here's how I think they could line up today.

Formation: 4-3-3

GK: Daniel Bachmann

No injury problems for the keeper, so he will keep his place.

RB: Kiko Femenia

One of the first names on the team sheet.

CB: Francisco Sierralta

He's almost a certainty to start at the moment.

CB: Christian Kabasele

Xisco Munoz will want to take no chances at this stage of the season and with Troost-Ekong's fitness still not certain, the Belgian could get his opportunity.

LB: Adam Masina

I'd be very surprised not to see him in the starting XI.

CM: Will Hughes

Hopefully can pick up where he left off with some consistently good performances.

CM: Carlos Sanchez

Did enough against Reading to suggest he's worthy of a start. Depends on Chalobah's fitness.

CM: Philip Zinckernagel

Will be looking to create and attack again today instead of getting caught up in a scrappy midfield battle.

RW: Ismaila Sarr

Week by week Sarr is looking increasingly threatening. He could have a big impact on this important week.

LW: Ken Sema

Hopefully will have benefited from the last week of no games again because he was starting to look a little fatigued.

ST: Joao Pedro

Hasn't scored in his last eight matches, but scored the winner against Luton earlier in the season and will be hoping he can do the same again.
