A fan has died after falling ill during Borussia Dortmund’s Bundesliga game against Mainz on Sunday.
A club statement said Dortmund were “full of sadness” after one fan passed away and another had to be resuscitated following two separate incidents.
Fellow fans watched the rest of Dortmund’s 2-0 win in virtual silence after news of the death spread through the stands.

The club statement read: “During the game there were two tragic incidents in the stadium in which two spectators had to be resuscitated.
“Unfortunately one person did not make it and has died. We are full of sadness and the families are in our thoughts.
