Before kick-off he posted on social media, "Come on Villa! Good luck in tonight’s Europa League final. UTV!" signed "W." After the victory he wrote, "Amazing night!! Huge congratulations to all the players, team, staff and everyone connected to the club! 44 years since the last taste of European silverware!" He also sent a special mention to Boubacar Kamara, who remains out injured but was praised as integral to the team’s success.
William has been a visible supporter all month — dancing to "Sweet Caroline" at a prior win and attending the FA Cup final — and he often appears at big matches in his role as a patron of the Football Association, where he sometimes presents trophies.
