The opposition:
Watford have had a mixed start under manager Slaven Bilic, following Rob Edwards' dismissal 10 games into the season.
The former Croatia and West Ham manager oversaw a 4-0 win against Stoke City in his first match in charge but has since lost three of his last four matches - the latest of which a 3-0 defeat at Millwall on Wednesday night.
They do, however, pose significant threats with Ismaila Sarr and Joao Pedro in particular.
The former has scored four goals and provided four assists in 11 games so far this season, whilst Pedro - who recently signed a new contract until 2028 - has four goal contributions to his name.
Last time we met:
James Collins came off the bench to score a penalty with his first touch to earn Luton Town a deserved derby victory.
