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.
Joselu cost 2.5 million, and his salary was 1 or 1.5 million, so you can say that Real got him for free, and he was able to score 10 goals. Joselu and in Al-Gharaf already scored 5 goals in 10 games, so honestly I don't understand why Real didn't want to keep him, because if you compare the cost of Mbappe and Joselu's goal, then as you described Joselu's goals were 30 times cheaper than Mbappe's.
Yesterday Mbappe still missed one 100% moment when he did not hit the goal and it was good that Bellingham took the role of leader and was able to score the first goal, so that Real led in the score first, and then Mbappe scored, but even with this score it was obvious that in the back Mbappe almost does not go, so the midfielders have to work in defense for Mbappe.
