A number of players including Arturo Vidal, Antoine Griezmann, Nelson Semedo, Riqui Puig and Samuel Umtiti were all spotted doing an exercise with snoods covering their faces.
Marca reckon the exercise was to help the players improve “coordination and orientation” and reckons it took them a while to get the hang of things.

It’s not the first time that Setien has taken an unusual, playful approach to Barca training. Mundo Deportivo have reported how he started off with a children’s game last week and seems to want his players to have fun and laugh in their training sessions.
