Chelsea manager Thomas Tuchel has explained what Kai Havertz must do to return to form following Thursday's 1-1 draw with Manchester United.

The German attacker spurned several good chances to score in the first-half at Old Trafford.

"He needs to fight back into his shape. Hopefully he shows a reaction," Tuchel told reporters after the game.

"The guys are still young up front," Tuchel said. "We will not start pointing fingers because lately they have been very composed and efficient. Against Southampton and the win in Bernabeu we took our chances very well.

"When we look at the data, we see a huge amount of sprints and intensity from Kai, and Timo as well.

"They don't arrive fully fresh at the moment, and that's why we will always protect them. We demand a lot off the ball, but I agree in the last weeks he had the form that would have put this game to bed."
