There were some massive red flags when Ole was given the job. Poch has at least had some EPL experience . Ole's appointment was proven to be a disaster.
Calling it a disaster is a hilariously bad take.
I don't know why you choose to be deliberately disingenuous at times.
I don't think three months is representative of Pochettino's entire career. I said that period (which was longer than 3 months - I lived with a Tottenham fan at the time I remember about him complaining about it) highlighted flaws and problems at Spurs Pochettino ultimately failed to deal with.
Given United has very similar flaws and problems, I think it's perfectly reasonable to question how he will deal with these problems differently at United.
