Why do you like him if you think he would fail at his first big job?
This one is a tough first big job. The team has a weird balance to it, I think the owner is either misguided or still finding his feet (hard to tell this early on), they are notoriously impatient, and the entire hierarchy around the owner has been replaced. Any under performance means being out of the UCL next year so he is under immediate pressure to get the team playing well, without a preseason.
Contrast that with taking over at City for example, or even a place like Barca who despite all their problems have a squad that is guaranteed to get them top four. On the other end of the spectrum, he could’ve gone to an Arsenal where he would be afforded a lot of time and resources.
It’s a bad combination of immediately needing to make an impact, at an impatient club, without a preseason or transfer window, and at a club that has gone through a lot of changes to all the staff that made it what it is in the past few years.
Which big job you take first matters, a lot. It affects perception going forward and his future chances of getting a similar job if he “fails”
