After the loss
The City midfielder feels City were guilty of trying too hard as they were beaten 1-0 in the first leg of their quarter-final against Tottenham on Tuesday.
After exits in the last 16 and quarter-finals in the past two seasons, transferring domestic dominance on to the European stage remains a challenge for City under Pep Guardiola.
Gündogan told Sky Deutschland: “We were not brave enough in the game and we made a lot of simple mistakes.
“I have the feeling we are nervous in important Champions League games. We always make the wrong decisions.
“In these matches we always want to do something special because it means (going through to the) Champions League semi-finals. Sometimes less is more.”
Gündogan believes City reacted badly to an early penalty miss by Sergio Aguero.

Gündogan thinks the game would have been much different had Aguero scored.
The 28-year-old said: “Negative events like that always set us back far too much.
“Had we scored from the penalty we’d have taken Tottenham apart.
“But instead we withdrew from the game. That must not happen to a big team. That’s why we’re not there yet.”
