This wasn't the performance of a top contender in a competition like the Champions League. Manchester City really need to get better. I know it is early of course but it is better to take precautions in time.
They have 2-3 more fierce opponents to face in this phase such as Juventus, PSG and maybe more as far as I can remember.
The result was beyond our expectations, I'm sure Haaland will score in this match. However, unexpectedly his performance was less effective. Inter played quite well, although City dominated the match as usual. Yan Sommer played very well, he was able to make five saves. Likewise with Inter Milan's midfielders, Simone Inzaghi's team was able to hold City to a draw at the Etihad Stadium. Regarding the point you said, I'm sure Pep will correct his team to the fullest. What is certain is that he doesn't like this result. I'm also quite sure that many people lost in betting on this match. In another match, PSG vs Girona, playing at the Parc des France, were only able to win narrowly. Even so, it was the Girona goalkeeper's fault. Unlike Dortmund, they played very well and were able to win by a landslide over their opponent.
