I feel the same like you, bro. Real Madrid appears to have several advantages compared to the manchester city, but i totally realize Manchester City is also a strong team like madrid. I am very concerned with the performance from real madrid to beat manchester city soon caused by it has some weakness that still remain unsolved. It seems to me if Real Madrid's lacks of a strong defenders in the defensive line who can prevent haaland to score in the upcoming game. I do not underestimate Eder Militao or anyone else, but this is Haaland.
The only capable defender who can go one on one with him is Rudiger. Last season's results showed that the city completely destroyed Real Madrid by a large margin. The result at Santiago Bernabeu worries me a lot since there are many things that doubted me. Madrid has not yet solved the problem due to a lack of good wingbacks and this can be the main weakness from the club.

Foden is still on fire and could be Real Madrid's biggest threat. I must admit that Madrid has an advantage because its opponent, Walker, lost one of the largest walls to Vini. I doubt Rico Lewis' performance, but Madrid's defensive line is significantly weaker than City's.
The competition in La Liga is not as strict as the EPL, which has so many big clubs competing for a trophy. Ancellotti stated that Real Madrid has some advantages over City, and he was correct, but Ancellotti's statement does not persuade me to choose Madrid.

I'd rather take a double chance on this match because there are several factors that have raised my concerns just like whether madrid's wingback is capable enough to prevent foden from scoring.
