Despite picking up four league wins and two draws since his appointment, the 47-year-old has acknowledged that Chelsea's approach may be stifling Werner's ability to run in behind as teams sit back and try to hit them on the counter.
"Maybe it is our fault because we have a lot of possession and we push opponent teams very, very deep in their half so spaces are not too big," said Tuchel ahead of his side's crucial home match against Manchester United on Sunday.
"The biggest strength of Timo is to attack the space behind the last line so it is maybe also our fault in the dominant game that we play in the moment, it is very natural that the spaces are closed by the opponents.
"A game like against Atletico, is there any team out there in the world that can close spaces like Atletico? I don't know.
"This is not exactly the opponent that you wish for Timo to show all his skills, so what is left for him is to not lose faith and work for the team. We are reflecting a lot about this and working a lot with him.
"There are also solutions in tight spaces to use his speed in the first metres, to use his acceleration.
"But it is not easy for him and I can totally see this. It is why I am very patient and very supportive and I believe in his potential and character and of course his goalscoring skills."
