The German champions dominated possession, but struggled to create chances as Atletico held out for their 33rd clean sheet of the season to take a huge step towards their second final in three years.

“We had talked before the game about how Atletico tend to start well,” said Guardiola, who will leave Bayern to join Manchester City at the start of next season.

“It is not a great result for us. It is always unpleasant to have not scored an away goal, but we still have 90 minutes.”

Bayern also lost the first leg of their semi-final in Spain to Real Madrid and Barcelona in the previous two years of Guardiola’s tenure.

And despite being on the verge of a third German title in as many years in Munich, Guardiola’s men must turn the tide if he is to avoid the embarrassment of leaving for Manchester without having conquered Europe.

“In the Champions League you need to use the full 90 minutes, which we didn’t manage here and didn’t play well for the first 15 minutes.

“We have to play more intelligently in the return match, we need patience and we only need a goal to take the game to extra time.”
