Chelsea boss Antonio Conte was full of praise for his players after they registered their second consecutive win in the English Premier League.
The Blues showed heart and determination as they scored two goals in the last ten minutes to take all three points from Vicarage Road.
They face Bristol Rovers in mid-week before hosting Burnley at Stamford Bridge on Saturday.
"I feel good because I saw the right commitment, the right spirit from my team," he told BBC Sport.
"This game wasn't easy this game because we were 1-0 down. I'm pleased to see the reaction from my players and this win is very important for us as it gives everyone confidence.
"It is wrong to come to Watford and to think it's very simple to win. In the first half I saw a good balance between the teams. I think we showed a great intensity in the second half and we pushed them a lot.
"I like to thank the fans because they pushed us on during the worst period. We must understand that we have to fight together and today is another game that we won at the end so it's very important."
