This was after the Belgium international granted a controversial interview about Chelsea where he said he desired to return to Inter Milan in the near future.
Lukaku in the interview aired last Thursday admitted he was unhappy with his situation at Stamford Bridge.
Lukaku came back to Stamford Bridge in a £97.5m transfer deal from Inter Milan in the summer.
In the interview, the Belgium striker further apologised to Inter fans for the manner he left the Italian side. He also said he considered Chelsea as a fourth choice when planning to leave Inter.
But Chelsea boss Tuchel has since admitted the striker’s comments did not help the club at his pre-match press conference on Friday.
The Blues boss is now considering punishing his striker, according to the report.
The punishment for the striker includes dropping him for Sunday’s Premier League clash with Liverpool, according to the report.
The German gaffer wants to leave the Belgian out of Chelsea’s matchday squad entirely as the player may also face a fine for giving an unauthorised interview.
