Thomas Tuchel has brushed aside suggestions that Edouard Mendy should be benched following Chelsea's 3-2 loss to West Ham on Saturday.
Since his £22 million move from Rennes last year, the Senegal international has established himself as one of the Premier League's best goalkeepers.
However, the 29-year-old had an underwhelming game against West Ham at the London Stadium, as he conceded a penalty in the first half by bringing down Jarrod Bowen in response to Jorginho's errant back-pass.
Mendy was then exposed for West Ham's winner in the 87th minute when he was unable to react quickly enough to keep out Arthur Masuaku's mishit cross.
Tuchel is adamant, however, that Mendy will retain his starting position during Chelsea's hectic winter schedule.
When beIN Sports asked Tuchel if he would consider dropping Mendy, Tuchel shook his head and replied, "I don't think so."
The German boss also urged his Chelsea players to cut down on 'individual errors' following their second Premier League defeat of the season.
"Five [goals conceded] in three [games] is not the problem, three in one game is the problem," said Tuchel.
"The problem is the goal we conceded against Man United was a big mistake by ourselves, we gave the goal against Watford away by a big, big mistake. Today was the same.
"If you do this, if we constantly give goals away by big mistakes we cannot have results on the highest level.
"We hate to lose, it happened today, we know why.
"We need to stay focused, reduce individual mistakes then we will have results."
