This. All managers start somewhere, our two former managers had very impressive CV's and it turned out pretty shite in the end. Hell, even if Fergie himself came back from retirement there is no guarantee he would secure a top 4, the same goes for Pochettino and Zidane. No one is denying Pochettino has done very well at Tottenham, but we are not Tottenham and he has not won anything yet. I mean getting outfoxed by Leicester in 2016 when basically all his major competitors were in the gutter is not very impressive.
Back to back CL wins from Zidane is impressive, but that Real squad was pretty insane and even then they did pretty awful work in the league. Many people called Emery a gamble when Arsenal hired him, and they have done quite well.
To be fair, i dont think Ole is ready and out the season is probably the best for everyone, but making a list of ridiculous, impossible demands like "Win the CL, bring world peace and make Katie Hopkins shut up" is a bit unfair. If he does well, his name should be in the hat like everyone else's
