Barcelona midfielder Arda Turan was one of the players who missed the open training session at the Mini Estadi on Friday.
Ernesto Valverde's squad trained in front of over 12,000 fans in the winter sunshine, but not everyone was available for the session.
Turan's suspicious reason for being able to train with the rest of his teammates, according to the club, was that he had a fever.
The Turkish international is more in than out at Camp Nou right now and this was another example of that. It's expected he will leave the club this month.
