Etienne Capoue believes Gerard Deulofeu is one of Watford's most important players.
Capoue says the Hornets covet Deulofeu's ability to win a game off his own boot.
"Before he signed we needed that player," Capoue told Premier League Productions.
"We signed him and he brought us the thing we missed offensively. He did it very well last season so I hope he will do much better. He has a big space to reach something else. I hope he will do it."
