The Germans won the Champions League quarter-final first leg 2-0 at the Allianz Arena.
"We certainly faced a very strong team and we didn't need tonight to tell us that. Bayern are among the favourites for the trophy and in my view were very fired up after losing the Final last season on home turf," the Coach told Sky Sport Italia.
"They are physically strong, have quality and great individuals. I cannot complain about what my players did tonight.
"We have to be honest and say the better team won on the night. Seeing as we are coming back to playing at this level, it has to tell us how far away we are from the top teams in Europe.
"We know football is unpredictable and it'll be an incredibly difficult task to go through, but we take it as experience and try to improve where we need to improve."
