Tuchel says his compatriot must find his ‘rhythm, confidence and joy’ in order to force his way into the starting lineup.
Werner is yet to start a game for Chelsea since the arrival of Romelu Lukaku from Inter Milan this summer.
The Belgium international hit the ground running in his first game against Arsenal as Werner had to settle for being a late substitute at the Emirates.
The Germany striker was an unused substitute in Chelsea’s 1-1 draw against Liverpool a fortnight ago.
While on international duty with the Die Mannschaft, Werner scored three goals and Tuchel seems happy with that but the former Borussia Dortmund coach is asking for more from the Chelsea number eleven.
"The most important is he finds his rhythm and confidence and joy and makes his point and makes his way into the team,” Tuchel told the media.
“The players are in charge to take their positions and fight for their positions and once they have it to not give it away.
"We are very happy that he scored and played (for Germany in the international break) and on we go. We have not too many players but we have players with high quality and high ambition and Timo is clearly a guy that we count on and that is absolutely necessary we have him on high level."
The German coach also revealed he is looking for a possibility of fielding Werner and Lukaku in the same lineup.
"I am sure that we will find games and solutions where we play with both of them (Timo Werner and Romelu Lukaku),” Tuchel added.
“We did already and Timo and Romelu can be a good fit together. Timo loves to play around a reference up front and Romelu is clearly our reference up front being a tall and physical player.
