Manchester City are weaker than themselves in early of season before Rodri injury and previous seasons, but they are now not too weak to easily beaten by Real Madrid. They can collapse like in the match with Arsenal, but they can play strongly in a match with Chelsea, it's how volatile and unpredictable Manchester City now, and it's a tough math for Real Madrid too.
But finally Man City had to admit the greatness of Real Madrid because even though the match took place at home they were unable to beat Real Madrid whose defense was not so solid. Even though Man City managed to score first in the 19th minute through Haaland, in the second half the tension of the game increased and Mbappe equalized the score to a draw, although after that Haaland managed to score again through a penalty and was equalized again to a draw by Diaz.
The added time was a disaster for Man City because Belligham scored the winning goal for Real Madrid again so that Man City had to suffer defeat at home. For the second leg it will be very beneficial for Real Madrid besides playing at home they also excelled in the first leg so it will be a little easier.
