A couple more things about Benitez at the RS.
His record in the transfer market was largely miserable. He bought in tonnes of players and paid absolute fortunes for them but very few were actual successes.
His biggest sporting achievement, the 2005 Champions League owed far more to the RS' deal with the devil than anything he did. They fluked the group stages, virtually every knock out round including the ridiculous ghost goal against Chelsea and of course they got utterly thrashed, embarrassed and humiliated for all but six minutes of the final. He basically did what Roberto Di Matteo did in 2012, but no one considers Di Matteo's fluke as anything other than a fluke and that's why no one hires him anymore.
His best achievements for me are the league titles at Valencia which were so long ago that he'd have some cheek actually including them on his CV.
He is not a good manager, and hasn't been for a while. I don't care about what he said about Everton, he was Liverpool manager at the time and it wasn't in his job description to be nice to us. If we were to have appointed him in 2007 it's actually something I could have got behind then, but in 2021?! He has failed miserably at Inter, Real Madrid, has been outperformed by Steve Bruce at Newcastle and did absolutely nothing in China of all places.
Lucien Favre, Rudi Garcia, Ernesto Valverde...we have options and don't need to go down this route. Benitez won't be afforded the same standards as any other manager, making it an almost impossible job. Why on earth would we employ a manager where every loss will be treated like doomsday?
