Watford manager Gianfranco Zola has expressed his relief at Ikechi Anya's return to fitness.
The pacey Scottish full-back made his comeback from a calf injury that kept him out for a month in Saturday's 3-3 draw at Leeds United.
"Ikechi is a lively player," Zola told reporters. "When you have him on the pitch he can transform the action.
"He can turn a chance for your opponents into a chance for you because of his pace."
Watford are without a win in eight games and have dropped down to 12th in the Championship.
