Watford have a 2-0 half-time lead over Leicester City in tonight's Championship encounter at the King Power Stadium.
The visitors need to avoid defeat if they are to keep their slim hopes of automatic promotion alive.
Following a frantic opening, Watford nearly took the lead on 18 minutes when Jonathan Hogg saw his rebound saved by Kasper Schmeichel after the goalkeeper had spilled Ikechi Anya's cross.
Leicester came close soon after, but Andy King's fierce half-volley from 20 yards flew inches wide of the post with Manuel Almunia beaten.
However, the away side made the breakthrough three minutes before the break when Troy Deeney converted from close range following Joel Ekstrand's header back across goal.
Watford doubled their advantage almost instantly as Nathaniel Chalobah lashed in an unstoppable strike from 30 yards.
