The Germany international has fallen down the pecking order since Romelu Lukaku's arrival and has started just two Premier League games this season.
He was an unused substitute during Wednesday's 1-0 loss to Juventus in the Champions League, despite the Blues being desperate for a goal.
It's been reported by the Daily Mail that Werner will consider a move if he continues to be overlooked at Stamford Bridge.
Werner has been desperate to make it at Chelsea despite a tough first season in England.
Despite winning the Champions League in his debut campaign, it was one to forget as a whole for the 25-year-old.
He only scored six goals in the league after a big-money move from RB Leizpig and this season hasn't been much better.
Werner's only goal so far came in Carabao Cup victory over Aston Villa earlier this month.
Back in May, Werner told the Telegraph he understands where the criticism comes from.
"I think a lot of people's expectations for me, outside the club but also inside the club, were very high because of my goalscoring record," he said.
"I also assisted many goals last year in my old club, but I think the main reason why they brought me here in the club is to score and maybe at the end 12 goals and six goals in the Premier League, that's not good enough."
His reputation back in Germany remains high and a move to Bayern Munich has been rumoured.
Tuchel also admitted in pre-season that Werner's lack of goals could be an issue.
He explained per Metro: "Nothing has changed so far. He had a so-so Euros with Germany, but that was a concern of the whole team not his personal problem.
"Now it's on him. Like always it's on him to show his quality and his ability.
"It's very hard to have a first match, first 45 minutes after a tough week that we put into the players, to play on this kind of level.
"I'm happy that he was dangerous but there were some chances where he could be more decisive, could have scored could have assisted another one or two."
