Watford manager Javi Gracia speaking to BBC MOTD:
"I think we had the confidence during the game, we started by conceding an own goal but after that the level was the same and in the second half we got the reward with two amazing goals. I am very happy with the performance and attitude of my players.
"All the games against Crystal Palace are always very equal, today was again. After conceding the first goal it was more difficult but we knew this team are conceding more goals in this period and it was our moment. We created enough chances to win the game."
When asked if it was good management to bring on Tom Cleverley:
"No, good player! The first half we had very good chances to score, and started the game with one clear chance to score. We continue and believe we are able to win the game and Tom was very important in that moment, like against Bournemouth. He is playing well after a long period injured. He is recovering his best condition.
"All my players deserve more time to play as they are all working very hard to play. I felt the best option was Tom and he scored an amazing goal.
"The next game is against Burnley, step by step and this is the best mentality to achieve what we want at the end of the season."
Watford's match-winner Tom Cleverley: "When you come to Selhurst Park you know you will have to battle, the games are nearly always decided by one goal or draws. Luckily I had enough quality to get the goal that won it. It was a bit unfortunate the own goal, and we are disappointed about not dealing with the first ball. Craig Cathcart has been outstanding all season we really appreciate his performances.
"I think it was a long throw and we won the second balls and it has come out to me and I took it on the volley. As soon as it left my foot I knew it was destined for the top corner.
"It is the squad we have got that helps us come back into games, people on the bench are ready to come on and help the team and we don’t let our heads drop. We can play good football or we can battle."
It's all over!
