*Everton Win League title in 1915 - League cancelled for four seasons because of World War, cannot defend title with best team since 1891
*Everton Win League title in 1939 - League cancelled for seven seasons because of World War 2, Everton unable to defend title with best team since 1932.
*Everton Win League title in 1985 and European Cup Winners Cup - English clubs banned from Europe for next five seasons, Everton unable to participate in the scheduled UEFA Super Cup Final versus Juventus, and unable to participate in Europe with that was their best team ever.
This always amazes me. Had World War 1 not happened, War World 2, or the English ban. Everton would have more than 9 league titles and one UEFA Cup Winners Cup.
