Javi Gracia underlined the importance of captain Troy Deeney after he scored and assisted in Watford's 2-1 win against Leicester.
Deeney nodded home inside five minutes to put the hosts ahead, before Jamie Vardy equalised in the second half. His cross was then slotted home by Andre Gray in the 93rd minute to seal a late win for Watford.
It earned him a Man of the Match award and the plaudits from his manager, who was also impressed with the rest of his team.
"I think everybody knows how important Troy is for us," Gracia told Sky Sports. "On and off the pitch, his personality, ambition and character for the game and out of the game as well. Today, he got the assist for the second [goal] and I think all of them made very good work.
"I am demanding with myself and I always have a lot of doubts about the players because all of them deserve to play. As Gray showed today, he is scoring goals for the team and the time he is playing, he is playing really well and all of them are important for the team.
"You have the reward at the end of the game. I thought we played well in the first half - better than the second. We started creating very good chances with Gerard [Deulofeu] after we scored and maybe in the second, we lost the possession and we had to defend. We then scored in the last minute and it is something amazing for us."
The result sees Watford stay in eighth but are now level on points with Wolves with nine games of the Premier League season to play.
He added: "There are nine games left and we already have 43 points so who knows what is going to happen in the next games, but what I can feel is the ambition, the character of the group and they always want more and more."
