Right, but how long was Mourinho at his first job before moving there? Not very long, Porto are also not a big stepping stone compared to us. Moyes has been at Everton for ten years now or something, how much has Mourinho accomplished in that time frame?
Klopp went to a Dortmund team with little expectations and was given time to rebuild, there was no pressure from the fans at all, that simply would not be the case here, if Moyes came here he would be under great pressure. He's inheriting a better squad of players at a bigger club than Klopp did.
Honestly, there's no comparison between his situation and the Klopp/Mourinho ones.
