Pep Guardiola thinks Manchester City lost their confidence after making first-half mistakes against Wolves.
The Premier League champions started brightly but were exposed on the counter-attack as Nuno's side pounced on errors as the Blues tried to play the ball forward. Fernandinho produced two blocks to stop one goal while Ederson pounced to deny Raul Jimenez a shot, but the damage had been done.
City's manager did not go into details over why the team became nervous and maintains they have the mentality and spirit that has seen them win the last two Premier League titles, but did reveal that they struggled to recover in the 90 minutes.
"It was a bad day, sometimes it happens," he said. "We started quite well and after we conceded two situations in our buildup where it's impossible to defend, we got a little bit nervous.
"We controlled them better in the second half but at the end with us attacking and people up front, we lost balls in positions it is so difficult and they were clinical. Before that we hit the post we had actions but the way we played was not good. It was not a good day, we didn't play good.
Asked specifically why the players were nervous, he answered: "It sometimes happens. We spoke about this: 'Come on guys, a lot of games to play, we did it and we're going to do it again'. We lost to a good team that were really well-organised, good physicality, strong in the air and so fast on the counter-attack. We knew it."
