Chelsea boss Thomas Tuchel rubbished suggestions the team was suffering a hangover from their weekend Premier League defeat to Manchester City.
The Blues have now lost two successive matches, albeit against very challenging opposition.
After the 1-0 loss to City, they lost by the same scoreline against Juventus in the Champions League in Turin on Wednesday.
Asked about the effect of the City loss, Tuchel told reporters: "No. We had a day off and two very good training sessions yesterday.
"We were absolutely sharp, looked very fresh and very hungry, and ready for a bounce back. It's very difficult to put on a high rhythm against a team who defends so deep. If we defended deep against City it was difficult for them to create chances. It was the same for us here. But the difference was we gave two big chances and gave the belief back into the stadium.
"Manchester City scored from a set-piece with a deflected shot against us. Sometimes you need this. If a team defends deep, it's hard to find your own rhythm. We were lacking runners. Once we started to do other things, we made mistakes and that cost us a bit of belief.
"A shooting problem. If we don't shoot, they cannot be on target. If you play against a deep block like today, it's hard to take shots. We found the spaces, it wasn't easy. We had a lot of shots, but I think there are some chances late in the game where it wouldn't have been so hard to find the target. I was liking the aggression we had yesterday.
"This game was a bit the same game against Atletico Madrid last season. It's difficult, but we can do better."
