Timo Werner has failed to live up to expectations since joining Chelsea from RB Leipzig last summer.
Julian Nagelsmann, his boss at RB Leipzig, has told Chelsea boss Thomas Tuchel how to get the best out of the Germany international.
Werner thrived under Nagelsmann’s guidance at Leipzig, leading the German club’s attacking charge with 34 goals from 45 appearances in all competitions last season.
Nagelsmann told The Telegraph: “Thomas [Tuchel] is a great coach and has shown in the past that he can make players better.
“Timo is a player that performs best when he is in his comfort zone, and I am still sure he will fit well in the Chelsea squad.
“Every striker goes through these periods once in a while. There have been times when Timo did not score in Leipzig as well. It is just a phase you have to get through.”
