Chelsea boss Thomas Tuchel expects a major challenge against West Ham tomorrow night.
Fourth-placed Chelsea go to West Ham, who are fifth, level on points with a superior goal difference, and manager Tuchel says he expects a "big challenge" at the home of the Hammers.
"We expect a tough match," said Tuchel.
"West Ham is very strong and they rely strongly on solidarity in defence, which is the basis for a very strong counter attack, which they have.
"The challenge is clear and to control the match we want to reduce critical ball losses to a minimum. That is the plan but it is a big challenge.
"Matteo Kovacic is still out and everybody else is available. The good news is that we are totally focussed on the game without any other subjects around."
