Many teams have this sort of transformation, for example in past years Milan won very little in the Italian Serie A championship and won many Champions Cups, in fact it is the Italian team that has the most Champions Cups. They are different behaviors or rather they are different objectives that are given to the teams. If a team focuses a lot on the Champions League it means that they will give up on the championship a little more, it's obvious, they can't do everything, it takes too large a roster of players to be able to do everything well.
