UEFA president Alexsander Ceferin has said that the Euro 2020 pan-continental format was not fair and should not happen again.
For the first time in the competition's 61-year history, the tournament has been held in multiple locations across Europe with 11 venues used, which was down from the original 12 that were initially chosen after games scheduled to be played in Dublin were moved elsewhere.
But with matches being played across London, St. Petersburg, Baku, Munich, Rome, Amsterdam, Bucharest, Copenhagan, Glasgow and Seville, some teams have had to travel thousands of kilometres in a short time to get to games, while travel restrictions have made it difficult for fans to support their country when matches were held at different venues.
"I would not support it anymore." Ceferin said. "I think it's too challenging, it's in a way not correct that some teams have to travel more than 10,000 k.m. and the others 1,000 for example.
"It's not fair to the fans. Some fans had to be in Rome and the next day or in a couple of days they had to be in Baku. A four-and-a-half hour flight.
"So it's a difficult one, it's an interesting idea but hard to implement and I don't think we will do it again."
Despite challenges with the format, Ceferin highlighted that Euro 2020 would be a memorable tournament.
"It's a special Euros, for sure." He added. "I will still remember the Euro as one of the most interesting Euros, at the beginning of normality, I hope, in the world."
