Chelsea boss Thomas Tuchel has revealed that Mason Mount will be unavailable for Saturday's Premier League clash with Manchester City at Stamford Bridge.
Christian Pulisic, as expected, is again absent due to an ankle issue, but Tuchel also said that Mount would miss out due to a "minor injury" that he suffered against Aston Villa in the EFL Cup on Wednesday night.
The England international has been an important player for the Blues this season, making seven appearances in all competitions, including four outings in the Premier League.
"Christian Pulisic is out and Mason Mount it's too soon. He has a minor injury from the Aston Villa game. He made a big step, huge progress, but not enough," Tuchel told reporters.
"He is very disappointed and I didn't feel it during the match because it was the second half and he played through the injury. He finished the game, was confident to take an important penalty. So it was a surprise.
The steps he is taking are huge, maybe it was possible if the game was one day later.
"So it's a minor injury but there is disappointment for him and us because he is a player that we count on. But no matter the importance, no matter how we rely on him, the task is to find solutions without him and bring him back as soon as possible."
The 22-year-old could make his return in next week's Champions League clash with Juventus.
