Through goals from Gabriel Jesus and Bernardo Silva, Manchester City won the first leg of their Champions League tie with Monchengladbach. However, Guardiola believes that the scoreline could have been more comfortable if his players were more clinical.
He told reporters in his post-match interview:
"In general we played really well. We were not clinical enough up front with the actions - the one against ones with the keeper, with the defender. We have to be more clinical in this competition, you have to be better.
"But in general, no complaints. I know how physical and how well-organised they are. They play with a diamond, they put a lot of players inside with Stingl, with Neuhaus and Hoffman, a player runs in behind her to defend a bigger space.
"It was a good game. Kyle Walker was exceptional today. The game he played, it was a good game - the first step and, many weeks until the second leg and now just thinking recovery for the game against West Ham in three days.
"In this competition, we don't have much margin. The actions, they will have one against one or three again two. In our position, you have to at least finish the action, make Sommer, the keeper, make a save and we didn't do it.
"We created a lot of chances arriving there in the final third. The process was good. We committed central defenders to arrive to the wingers in that position and we have to finish better.
"And in this competition, you have to improve. But it was just today it didn't happen, another day it will be another player. They have to know that in this competition - because in Premier League always we can drop points but you have a margin. In this competition, you don't have a chance."
