If you guys hire Mourinho you will win the Premier League most likely, after spending millions upon millions. You will win after selling all of your young players down the river, which imo would be a travesty because as a fan of another club I love that the club has kept with tradition. Man Utd are my favourite club other than my own because of it's traditions and values, and it's rise through the years to become a superclub.
Mourinho is a winner but his football is soulless and I could see the young players (Rashford, Lingard, Fosu-Mensah, Varela, Januzaj) getting benched indefinitely. That IMO, would be a travesty.
Yes, Mourinho may keep the players like he kept many of Ranieri's players... but I don't see it happening because he would be so desperate to beat Pep that he would destroy their careers to grant himself instant success. Mourinho is a footballing parasite like that, he does not build empires. He takes finished products (players) and then wins with them. This team is not the finished product by any means.
The best option imo is Simeone, a guy that has shown he can nurture young players and win. Also, his style of football would prove to be effective in the PL. If Simeone wins the CL his job with Atletico is done surely... where does he go from there? Everything should be done to get Simeone. Not easy to lure away from Atletico, but he is a damn sight more appealing than Mourinho.
