Manchester City boss Pep Guardiola told BBC Match of the Day: "We did not create enough for the forwards. It is part of the game.
"In the last 10 minutes they had other chances, they are fast and can do it. When they defend in the way they were doing you have to stop them running and we did not do that.
"We are going to rest and prepare two days for the game in Dortmund and decide on how we are going to play."
Leeds United boss Marcelo Bielsa told BBC Match of the Day: "The value of the victory increases because it was achieved in a game where we were dominated and demanded character, effort and personality.
"I think we have to link the victory to the spirit of the players. The spirit of all the players added together creates a uniform effort. It's very difficult to win games like today. I think we deserved it but the fair thing would have been for City to win it because they had the dominance and the chances.
"I value a lot the English refereeing and with the added factor of VAR all the decisions are justified."
