Watford are hoping for an FA Cup third round upset this evening as they face Premier League high flyers Manchester United. 

Head coach Xisco Munoz has said his side are going to Old Trafford with the intention of progressing to the next round, however the club's priority this season is definitely getting promoted back to the top flight.

Here's how we think they will line up.

Formation: 442

GK: Daniel Bachmann

This competition represents Bachmann's only real chance of getting game time this season, unless Ben Foster gets injured.

RB: Jeremy Ngakia

I would not be surprised to see Kiko Femenia rested, or at least starting on the bench.

CB: William Troost-Ekong

One position where Munoz has options for changes. Cathcart is available again, but may not be starting.

CB: Francisco Sierralta

This could be either Sierralta or Wilmot, but I think due to Wilmot being a more regular first team starter, Munoz will opt to play the Chilean for tonight's less important fixture.

LB: Adam Masina

A chance to get Masina more minutes, this time from the start, against good opposition. Would expect him to be replaced around the 60 minute mark.

CM: Tom Cleverley 

The midfielder should start against his former club, with Hughes still a couple of weeks away from starting matches.

CM: Philip Zinckernagel

I expect the Dane to make his debut today, with options in central midfield lacking at the moment, given Capoue's departure, Hughes's lack of fitness and Garner not being permitted to play against his parent Club. I'd expect Cleverley to sit deeper and Zinckernagel to play as a number 10 behind the strikers.

RW: Ismaila Sarr

Will get the chance to show Man United what they missed out on when they failed to sign him in the summer transfer window.

LW: Ken Sema

If Zinckernagel plays through the centre, there aren't many other options for the left wing with Joao Pedro unlikely to start.

ST: Troy Deeney

The captain will keep his place, but has a lot to prove after a bad game against Swansea.

ST: Andre Gray

There isn't much room for rotation up front at the moment, so it looks likely that Gray will keep his spot.
