Romelu Lukaku did not mark his return to the Chelsea side with a goal but earned praise from boss Thomas Tuchel after Wednesday's 2-0 League Cup semi-final win over Tottenham Hotspur.
The Belgian striker had apologised on Tuesday for saying in a TV interview he was dissatisfied with his role at Stamford Bridge since joining from Inter Milan for a club-record fee of 97.5 million pounds ($132.5 million) in the close season.
