William, Prince of Wales, was one of the more noticeable Aston Villa supporters in Istanbul as he watched the team win the Europa League against Freiburg on Wednesday night — and the UK’s future king then followed up by celebrating with the squad at their hotel.Post-match, the prince travelled to where Villa’s team were staying in the Turkish city to toast the club’s first major trophy in three decades.It was part of a short trip out to follow his favourite football team, including visiting to their dressing room before and after to wish them luck and then celebrate, as well as being pictured on TNT Sports — the broadcaster which screened the match back in the UK — jumping around in the stands when Villa scored in their 3-0 victory and posing with the club’s manager Unai Emery.The after-party, arranged for the players, their friends, families and agents, began once the squad returned from the stadium at around 2.30am (the match ended around midnight local time) and continued until about 6am.William, an avid Villa fan who has told other supporters he goes on fan forums using a secret identity, mingled with the squad and their relatives, along with Emery and his staff, happily chatting and enjoying a drink. Sources, speaking anonymously to protect relationships, said people were very impressed with his level of understanding and detail about the game.In a social media post marking the victory on Wednesday, William singled out midfielder Boubacar Kamara, who had to miss the final through injury, for particular praise.
