Chelsea boss Jose Mourinho expects a tough test tonight against West Ham United.

Mourinho admits he admires their new-look attack.

"West Ham are a good team," he said. "They can be everything: defensively very strong, very dangerous in attack, very dangerous playing direct football with long balls to target men, and also very dangerous attacking spaces and trying to play on the counter-attack with fast people like [Diafra] Sakho and [Enner] Valencia.

"They have in their hands different ways of playing football and thinking about the game. With a very good coach like Sam it's always difficult to play them."
