Al Nassr already has an European coach. Luís Castro is a Portuguese and has managed big clubs in Europe, such as Shakhtar Donetsk and FC Porto, and also the Qatarian side Al-Duhail Sports Club. We shouldn't start criticizing him now since these games are just preparatory to the main league events.
I didn't say Al Nassr has no European coach. I said Al Nassr didn't hire a top European coach. What big clubs Luís Castro ever managed? Donetsk and FC Porto are not very big teams in Europe. These teams even aren't a part of big leagues in Europe...
The Saudi league is not a very big league and Al Nassr is not such a big team that it needs a super coach. To give you an idea of what I'm talking about, before Luís Castro became the coach of Al Nassr, he was the coach of Botafogo, which is a team in the first division of the Brazilian league. The Brazilian league is much better in terms of quality when compared to the Saudi professional league. While Luís Castro was the coach of Botafogo, I saw Botafogo playing very well, to the point that they were at the top of the league and looked like a team that could compete for the title.
But as soon as Luís Castro left Botafogo, Botafogo's performance dropped a lot. This clearly showed that Botafogo was performing so well because of Luís Castro. As the coach of Al-Duhail SC, he didn't win the Qatari league, but as the coach of Shakhtar Donetsk, he won the Ukrainian league.
FC Porto is a team that can play and surprise the big teams in the European Champions League. Porto is not underestimated in the European Champions League. Luís Castro was not the head coach of FC Porto. He did not win the Portuguese League, which is not an easy league to win unless you are a good coach and are working at Porto, Benfica or Sporting. But overall, I think that Luís Castro is not to blame for all the bad things that have happened to Al Nassr. Even if Al Nassr hired the coach of Real Madrid or Zinade or even the coach of AL Hilal, they still would not win anything, because they are a team centered on Ronaldo, who is no longer in the best condition but does not sit on the bench, so it will be difficult for any good coach.
