Granit Xhaka, the new Arsenal midfielder, had to change his jersey twice during the Group A game, while Admir Mehmedi and the striker Breel Embolo also required replacements following tugs that did not appear especially vicious.
“We have had a few problems with the jersey,” Embolo said. “The kit manager is not fully ready yet, but we are.”
Yann Sommer the goalkeeper added:
“It can happen. It means it was a fight on pitch.”
A Puma spokesperson told the Guardian:
“Five Puma teams have played 10 games in this tournament without such problems. Our product people are currently investigating the shirt material. We will provide a further update when we have one.”
