Slaven Bilic could use Troy Deeney's dig at West Ham to inspire them to gain revenge over Watford.
Hornets skipper Deeney accused the Hammers of being 'disrespectful' after their meeting at the London Stadium in September.
The hosts led 2-0 after half an hour thanks to two Michail Antonio headers - the second from Dimitri Payet's rabona cross - but Watford hit back to win 4-2.
Deeney claimed West Ham's so-called showboating fired up the Hornets, but Bilic says his side have plenty of motivation to turn the tables in late kick-off at Vicarage Road.
