Actually, I personally am also not satisfied with Real Madrid's performance, especially Mbappe, indeed he has the best chance to score a goal, but somehow he can do that and it is true that if Mbappe can take advantage of the opportunity well, of course he will create a hat trick, but yes, fortunately for Real Madrid win and Mbappe scores a goal, just imagine if for example Mbappe didn't score then Mbappe would definitely be embarrassed by Real Madrid fans, but fortunately he scored a goal and Real Madrid could win, and I really like his style of celebration (Mbappe) is good.
Mbappe wasted many chance, if he can only score one or two goal(s) in every match, there's nothing different between him and Joselu.
You know, Joselu only got paid for 2.5 Million Euros, while Mbappe get paid 31 Million Euros, which is 12x times higher than Joselu, but he didn't bring the same 12x qualities.
However, we shouldn't forget Ronaldo was been hated by the fans since he didn't perform in Real Madrid. But, after few months he can show if he deserve to play in Real Madrid.
