Spanish football expert Guillem Balague has hailed Celtic’s 1967 Euro triumph and domestic Treble as “perhaps the most precious” of all. The Lisbon Lions were the first club to complete a full set of league, domestic cup and European Cup when they beat Inter Milan 56 years ago.
Only six other clubs have followed suit since – Ajax, PSV Eindhoven, Manchester United, Barcelona, Inter and Bayern Munich. But Manchester City could join the illustrious group on Saturday when they take on Inter in the Champions League Final in Istanbul having already won the Premier League and FA Cup.
That sparked a debate on BBC 5 Live over which achievement stands above all others. And Balague – who has penned a biography of City boss Pep Guardiola’s trophy-laden managerial career – reckons Jock Stein’s Hoops might just edge it for one specific reason.
