Jose Mourinho has said that he is expecting a "difficult match" against West Ham United tomorrow.

Chelsea travel to Upton Park tomorrow evening to face their London rivals, who currently sit 16th in the Premier League table.

The manager told reporters: "They are defensive and they give difficult matches to the big teams. That's why everybody is losing points, why no team is dominant, why everybody is losing points but keeping in contact at the top of the table.

"That's why this league has emotion every weekend, so I'm expecting a very difficult match.

"We have to do better, we've had very difficult matches away, I think our fixtures until now were not the easiest, especially away."

Chelsea have just one win from their last three league games.
