BBC Sport: The game came to life in 10 first-half minutes as Joao Pedro lifted the ball over Thomas Kaminski to give the Hornets the lead before Ismaila Sarr scored from close range five minutes later.
Sky Sports: Harvey Elliott spectacularly gave Blackburn hope before the break, but the Hornets regained control just after the hour through Ken Sema’s pinpoint finish. Ben Brereton made it a nervy finish but Watford should have had the game sewn up by that point, with Sarr thwarted by Thomas Kaminski, and one cleared off the line at 3-1.
BHappy: The evening was pretty brutal all round. It was hammering down with rain on a heavy, tatty-looking pitch. Blackburn were on the back of a four-match losing streak and missing players. We, of course, are also missing players… Foster, Kabasele, Chalobah, Deeney is at the very least a respectable spine for a Championship side. This is the point in the season where the depth of our squad ought to tell.
