In short
He won the CL even though he had his best 2 players out (suspension) - hence his quality is slightly lower than his opponent. His opponent stats were much better than him
He lost the Cup final even though he has a one man advantage. His quality is much better than his opponent. His stats were better than his opponent

Got it?
Cup - higher quality and better stats - but lost to a ten men team of lower quality
CL - the reverse happened
Cheers
