Olmo returns to training as Lewandowski faces doubt for Mallorca opener

The Spanish midfielder had missed the Joan Gamper Trophy match due to muscular overload, but rejoined team activities after a brief spell away from full training. His recovery comes as welcome news for the Catalan side.

Lewandowski, on the other hand, continues to struggle with a left hamstring injury and did not train with the squad.

The Catalans have yet to announce a definitive timeline for the Polish striker's return, putting his participation in Saturday's fixture at Son Moix in serious doubt.

Flick's session also featured academy players Toni Fernandez, Guille Fernandez, Jofre Torents and Pedro Fernandez, all of whom took part in Barcelona's recent Asian tour.

Before training, the squad attended a standard briefing from the referees' technical committee, a routine part of the preseason schedule.

With preparations now underway for the season opener in Palma, Barcelona will train daily at 09.30 CEST. Flick is scheduled to hold a pre-match press conference on Friday at midday, with the first 15 minutes of training open to the media.
