Sometimes numbers do not say whole truth until you add even more numbers :)
He lost with Barcelona the CL semis against Inter and Chelsea when park the bus strategy was adopted and Barca completely dominated the games but couldn't score. Against Inter, Barcelona had 42 total attempts(YES 42!) in the home game but....
Same with Atletico Madrid where Bayern had 34 attempts with 12 on target at home(versus 7 total of Atletico), only to win 2-1(xG goals calculated at 4.12-0.25 if I recall). They dominated away game also only to lose 1-0 and eliminated on away goals.
Against Real Madrid Ronaldo scored twice from an offside position, Bayern did not get a cleal penalty and a red card was gifted to Real Madrid. UEFA gifted that semi final series to Real Madrid.
Against Barcelona, Bayern I recall had many injuries and Messi was on top form so unstoppable.
Last year against Real Madrid, City dominated both games, especially the home game where score should have been 6-3 easily. But..... And 2nd game at Madrid, Real M. was not dangerous at all and City controlled the game but those damn 5 minutes....
