Having won each of their last three matches in the EFL Championship, Watford are in excellent form. They are only outside the automatic promotion spots because of goal difference.
Swansea, however, have just a point less than both Watford and Brentford, and have two games in hand.
The Hornets are sitting rather pretty within the top six, and barring a spectacular collapse in the last 15 games of the season, should make the playoffs at least.
In their last game, Watford held on by the skin of their teeth to beat Derby County 2-1 at Vicarage Road.
Joao Pedro and Will Hughes scored in the first half to put Xisco Munoz's side on their way. Derby were excellent in the second half, but just could not force the equalizer. However, they did halve the deficit through William Troost-Ekong's own goal.
For Blackburn, the inconsistency that they have shown throughout the season continues to plague them. Rovers currently find themselves 10 points adrift of a playoff spot, after losing their last four league games.
In their last match, Blackburn were beaten 1-0 by Nottingham Forest at the City Ground.
