Sportswear manufacturer Puma is investigating why the shirts of four Switzerland players ripped during their Euro 2016 match against France, reports BBC Sport.

Midfielder Granit Xhaka had to change his shirt twice in the first half after it ripped up the side.

"Seeing our shirts being ripped in a match was the first time we have experienced such an issue," Puma said.

"Five Puma teams have played 10 games in this tournament without such problems. Our product people are currently investigating the shirt material."
