Hakim Ziyech looks set for a lengthy spell on the sidelines after Thomas Tuchel said that the player had sustained a ‘serious’ shoulder injury in the Uefa Super Cup win over Villarreal.
Ziyech had shone across Chelsea’s pre-season matches and opened the scoring with a close-range finish in the 27th minute on Wednesday.
But he was forced off after a collision with Juan Foyth at the end of the first half and Christian Pulisic replaced the Moroccan before Chelsea prevailed on penalties.
‘If you take a player out during the first half, it’s serious,’ Tuchel told BT Sport when he was asked to reveal the severity of Ziyech’s injury.
‘It’s unfortunate because he was a very decisive player for us in the last few games.’
Tuchel conceded several Chelsea players had been ‘overused’, with just days separating the Super Cup and their Premier League opening game against Crystal Palace.
‘Physically, it [120 minutes and penalty shootout] was the worst thing that could have happened to us. Mentally and psychologically, this was the best thing to start with a trophy because there was no way to delay the game or play it in four weeks,’ Tuchel said.

‘This was the moment where we needed to start and that’s why we chose this line-up. We didn’t want to break our heads and share minutes. We had all these discussions, do we continue the preparation phase and use this match to get ready for Saturday?
‘And then we decided no, we use this match to win and nothing else so we went with the team that played already against Arsenal, that played already against Tottenham, to be in the best shape possible.
‘Are we 100 per cent of our capacity? No, absolutely not. But we are ready to play football matches on a certain level.
‘We had to suffer because you could see that after 35 minutes, things got a bit hard for us. We had some easy ball losses, it was harder to close spaces and unfortunately it continued like in the second half.
‘They deserved their equaliser as we had easy ball losses, we finished our attacks too early and we allowed chances. I was very impressed by our reaction after 75 minutes, we had total control of the game again and played a very good match until the 120thminute.
‘So there are a lot of good things. Physically, we overused some players who were absolutely not ready to play 120 minutes and we have only two days in between the next match with Crystal Palace but this is the schedule.’
