Manchester City boss Pep Guardiola admits Leeds United's hard running was too much for them after defeat on Saturday.
Leeds won 2-1 thanks to Stuart Dallas' brace and despite Liam Cooper's dismissal.
Guardiola later said, "We played a real good game. The goal we gave them, in behind, we were solid and make mistakes for a counter attack. We did not control it. We did not create enough for the forwards. It is part of the game.
"In the last 10 minutes they had other chances, they fast and can do it. When they defend in the way they were you have to stop them running and we did not do that. The best moment we had in the game we make a mistake behind and we tried but could not score.
"We are going to rest and prepare two days for the game in Dortmund and decide on how we are going to play."
