“We have to be ready to control Zaha. But we also have to control Townsend and to control all the players they have.”

Gracia knows from experience that Palace usually provide a tough test and he expects this weekend’s clash to be exactly the same.

He said: “We know all the games are very demanding, in this case, we have played against Palace last season and this season and all the games have been very equal.

“I don’t expect anything different in this case, I know it will be very demanding.

“We are ready to play and compete and try to get a good result.”

Watford bagged all three points earlier in the season with a 2-1 victory over Palace at Vicarage Road and Javi Gracia’s men will be looking to repeat that feat to climb higher up the table into the top ten.
