Roberto Martinez praises West Ham United mentality

Everton manager Roberto Martinez has predicted that his side will have to fight hard in order to gain a result against West Ham United at Upton Park.

The Hammers have won six of their 11 Premier League fixtures this season, which includes victories over the likes of Manchester City, Arsenal and Chelsea, and Martinez has praised the changes made by opposite number Slaven Bilic.

The 42-year-old is quoted by BBC Sport as saying: "Slaven plays in a very different way to the one West Ham used to play.

"As an ex-Evertonian, we know he is a competitive man. He gained invaluable experience when managing Croatia and his teams are always ready to compete.

"From a psychological point of view, to go to places like Manchester City, Arsenal and Chelsea and win shows they have a fantastic mentality."

Everton can move to within one point of sixth-place West Ham with a win in East London.
