Watford manager Walter Mazzarri admits Crystal Palace's woes this season have surprised him.

As the Hornets prepare to face the Eagles at Selhurst Park on Saturday, the Italian says he would not usually expect the South London club to be involved in a relegation fight.

Palace sit 17th and Watford 13th ahead of the weekend's clash.

"They are one of those teams that, when you look at their squad, nobody thought when we started they would have fought relegation," said Mazzarri.

"The game will be decided by individuals. In order to have a positive outcome my players have to come to the pitch with their legs and their heads in perfect condition.

"They (Palace) are on a good run, are in good form and are in good condition. We will play them in their best moment as they come from two positive results. They've got an important fan base so it won't be easy.

"We go to the pitch knowing we cannot commit any mistakes. We have to go there and give everything in order to come out with a positive outcome.

"From now, all games will be extremely difficult and different from the first half of the season. They will all be battles, they will all be finals."
