"Liverpool" coach Jurgen Klopp criticized UEFA's schedule.
According to the German, players can get injured when they have to play in the Nations League finals without a break after the club season.
"On June 1st, we will compete in the decisive Champions League match in Madrid, and already on June 6th, a wonderful tournament called Nations League will take place.
Everyone looked at me when I previously called it a bad idea. And now - surprise: two English teams have reached the Champions League final.
If you can't handle such things with your football players, there is a serious threat to ending this wonderful game.
Of course, it's not the fault of coach Gareth Southgate. Interesting planning and later amazement when two English teams play in the Champions League final," the German clarified.
He also criticized UEFA's decision to hold the Europa League final in Baku, Azerbaijan, and the exorbitant prices for fans in Madrid.
"It's a strange decision. I don't know what the organizers eat for breakfast when they come up with such things. Last year we went to Kiev - a wonderful city. But it's hard to believe that a team from another part of the world will be involved in this matter.
Madrid will have to be prepared to welcome 200,000 English fans. But such decisions must be made more carefully.
Perhaps these cities should agree to reduce the costs of hosting fans? One hundred pounds for a hotel stay, not 2700 pounds. In this case, I definitely support the team's fans," Klopp said.
