Benching experienced players like Frenkie de Jong is disrespectful. Frenkie is being treated very badly by Xavi, he should continue starting the game, and Busquest should be benched. In the coming transfer window, he must move to a better club.
Actually, Busquest and Frenkie have different positions. Busquest is a defensive midfielder, while Frenkie is a central midfielder. Ideally, Busquest should leave Barcelona because his quality is no longer suitable to play as the main player there. Busquest has decreased a lot in speed, he seems very difficult to deal with fast players like Vinicius, Rodrygo, or Valverde. That may be one of the reasons why Barcelona was defeated in El Classico. So, I think Xavi must sign a new defensive midfielder in the next transfer window. While for Frenkie, he deserves to play as the key player in Barcelona. I assume his quality is still better than Gavi or Pedri.
Mourinho gives the result - he won the Champions League with two different clubs. The fact that he is allegedly eccentric is hardly of concern to someone who looks at football and not at the image or how Mourinho trolls opponents.
I know it, I was a fan of Mourinho. Especially when he managed Inter Milan and got Treble Winner (2009–2010).
But it was many years ago, we must look at the reality of his current achievement. I think there are many other coaches who are better than him. Moreover, if you compare him with Guardiola, surely no reason to claim Mourinho is better to replace him as Man City coach. Only a person like Zidane who deserves to replace Guardiola's position.
I completely agree with what you said about Mourinho and his "good old times". It was amazing how he strategically beat the big teams with Inter, but also when he won the title in the Champions League with Porto of course. It was also fun to follow him, to follow his press conferences. At some point it felt like he is getting lazy and taking things too far.
The reasons could be manyfold and I do believe that saturation, money and along with that his age do play a role. Then there are also coaches who prove the opposite. After all he is probably doing something many people would do: he uses his reputation he built in the past the hard way to earn money in the future the easy way. He knew that he could only win with Roma. When they finish 6th, nobody cares, when he wins the Serie A with them, he is the king in the world of soccer.
