West Ham United boss Slaven Bilic believes opponents Watford will be helped by fielding a team with fresh legs tomorrow night.

The Hornets will make plenty of changes for the trip to Upton Park with one eye on their FA Cup semi-final on Sunday.

Bilic said: "On one hand they will probably think a bit about the game at the weekend, and maybe they will rest some players.

"But they brought a lot of players, experienced players, in the summer and in January.

"They have a big squad and a certain way of playing, and players who maybe start on Wednesday will have some fresh legs which is good for them."

Bilic, whose side are sixth in the Premier League, said: "No matter which team they put out we need a win. The gap (to fourth place) is big, but the gap can be reduced.

"We have to win games. We are still in a big race for Europe and we are going to do everything we can."
