Pep Guardiola refused to get too disheartened after seeing Bayern Munich throw away a two-goal lead against Manchester City.
European champions Bayern burst out of the blocks in their latest UEFA Champions League outing and established a commanding advantage just 12 minutes in - with Thomas Muller and Mario Gotze on target.
They were, however, to end up being humbled 3-2 on home soil.
City, who knew they had to win convincingly to stand any chance of topping Group D, hit back on 28 minutes through David Silva.
With Bayern rattled, the Premier League outfit struck twice more after the interval through Aleksandar Kolarov and James Milner to stun the Allianz Arena.
In the end, City's efforts were not enough to prevent Bayern from edging into the last 16 as table toppers and Guardiola was able to rest a little easier at the final whistle.
He told Sky Sports: "When you play in Europe and you play against good teams like Manchester City, always this situation can happen.
"You have to accept this defeat and understand how difficult it is to come back and to play good."
Guardiola admits a setback may be no bad thing for Bayern, with the German giants currently enjoying a 40-match unbeaten run in the Bundesliga.
The Spaniard said: "Perhaps we needed a defeat to remind us of a few things.
"We have made a good start in the league, in the cup, in the Champions League, winning in Manchester, perhaps we thought things were too easy.
"Congratulations to City, I also congratulated my players in the changing room for finishing top of their group.
"The most important thing now is that we learn the lessons from the defeat."
