Pep Guardiola conceded Manchester City felt pressure from their previous Champions League failures in a nervy 2-1 quarter-final win over Borussia Dortmund.

Phil Foden struck in the 90th minute to ensure the Premier League leaders will take a slender advantage to Signal Iduna Park for next week's second leg.

Marco Reus had equalised four minutes from time for Dortmund, with City struggling to find their fluent best with any consistency after Kevin De Bruyne's first-half opener.

"We felt the pressure today for this competition at home. We don't know how we are going to play," Guardiola told BT Sport.

Liverpool, Tottenham and Lyon have ended his team's involvement at this stage over the past three seasons.

"Now we know each other better," Guardiola said. "We are going to analyse what we have to do, like we have done for five or six months, playing every game to try to win."

Dortmund were understandably furious to have had an initial equaliser ruled out before half-time, when the impressive Jude Bellingham was harshly adjudged to have fouled City goalkeeper Ederson before rolling the ball into an empty net.

Guardiola suggested City's struggles that led to that let-off were part of a wider issue with their usually smooth build-up from deep failing to click – highlighting a tough outing for holding midfielder Rodri and full-back Joao Cancelo.

"To play good in the areas that we want, we need to make a good build-up and today was not good," Guardiola said.

"Joao and Rodri were not clever to receive the ball in positions to contact for the other ones. But it’s normal, Dortmund are strong. The quality that they have makes it difficult to do what we want to do.

"We are going to watch the game, now we know exactly what they do and now we are going to adjust a few things to go there to Germany and try to win the game."

Foden shone for his boyhood club throughout and was relieved to atone for a pair of missed chances that preceded Reus' leveller.

"Second half he was a threat for them. He played really well one-against-one, arriving in the final third," Guardiola added.

"He had two or three clear chances to score and finally he scored the goal."
