Football fans have criticised the price of tickets for next year's World Cup, with one fan group calling on FIFA to stop the sale of tickets. According to Football Supporters Europe (FSE) — which represents fans across the continent — the tickets for the competition in the United States, Canada and Mexico, running between 11 June and 19 July, will cost almost five times more than the 2022 edition in Qatar.
