Google says it was because they won 1901 FA Cup as a non league club so they wore similar shirts even though they won't win the FA Cup 2026 😄 also Google says there were only Div 1 and Div 2 in those days and the Southern League , that Spurs were in, was a mixture of profesional clubs and part timers but still a strong league . So not such a big gap as CP and Macclesfield sides !
