Watford manager Aidy Boothroyd admitted Tuesday's 1-0 win over Leicester City was "massive" after keeping his side at the top of the Championship table.
The Hornets survived the first-half dismissal of John-Joe O'Toole to claim the points courtesy of Darius Henderson's strike and afterwards Boothroyd praised the resilience of his players.
"If Saturday's win at Ipswich was a big one then this was massive for us," he told the club's official website.
"It is going to go right to the wire and we have to make sure we're disciplined enough to grind out results.
"It was a bit of a fighting start, they've got a terrific defensive record and you can see why because they throw bodies in there.
"The crowd was fantastic, the decision brought everyone together. We've had two very good wins and the crowd is with us again."
Meanwhile, Boothroyd has suggested he will appeal O'Toole's red card which was controversially awarded for denying Stephen Clemence a goalscoring opportunity.
"I didn't think it was a sending off but I'm going to have a proper look at it on the playback and we'll contest it if it what I think it is," he added.
"Apparently he has denied a goalscoring opportunity."
