Ange Postecoglou’s tenure at Tottenham Hotspur culminated in a historic Europa League victory in Bilbao, ending a 17-year trophy drought and marking the club’s first European title in 41 years.
Despite this landmark achievement, Postecoglou’s exit from Spurs was clouded by internal discord and dissatisfaction with league performance. The club’s leadership, while acknowledging the European success, was concerned about the team finishing
fourth-bottom of the Premier League, a position deemed unacceptable.
James Maddison, Spurs’ vice captain, expressed deep gratitude for Postecoglou’s impact, writing on X:
"You led us to victory and we’re European champions and in this club’s history books because of you and your winning mentality." He also praised Postecoglou’s character, calling him
"a family man with great morals" and highlighting his
"unwavering self belief and strong mindset" as key to ending the club’s long trophy drought.
However, the high-intensity style favored by Postecoglou became increasingly unsustainable due to a squad plagued by injuries and exhaustion. The club’s management credited him for adapting but ultimately decided a change was necessary to avoid a fate similar to that of Manchester United under Erik ten Hag, whose struggles last October served as a cautionary tale.
This combination of historic success and underlying challenges paints a complex picture of Postecoglou’s Spurs era, where triumph was shadowed by a mutiny over league struggles and squad management.
