But when Bayern sealed a record-extending fifth consecutive Bundesliga crown on Saturday with a 6-0 demolition of VfL Wolfsburg, most of them also breathed a big sigh of relief, knowing that the world was still in order.
Bayern had gone through what amounted to a mini-crisis in recent weeks, failing to win any of their last five matches in all competitions and being eliminated from the German Cup and Champions League.
After hopes of a possible treble-winning season drained away, Bayern saw their Bundesliga lead shrink from 13 points to seven before Saturday's win.
Their late-season wobble, however, never really put their championship chances at risk with Ancelotti's team having done all the heavy lifting earlier in the campaign to make sure they remained the dominant force in Germany for yet another season.
"The Bundesliga comes first," Bayern CEO Karl-Heinz Rummenigge had said, with each coach, including Ancelotti, making the league win their top priority.
