Watford boss Javi Gracia says Troy Deeney is a crucial influence on his plans.
Deeney came from the bench at Southampton for Saturday's 0-0 draw to make his first outing since suffering a hamstring injury in early October.
“I think it is very important and I want all the players to be fit. That is the most important thing for me," Gracia said.
“Speaking about Troy, playing with Andre they were very important in the first games. They played well and scored goals.
“In this moment I think we are stronger with Troy back and he gives us another option up front."
