The idea that INEOS interviewed people but thought he was the best candidate still is laughable. As though it's an interview process like we go through, where they have no idea who we are, instead of our every move being plastered on SSN every day, or they watch them carrying out their job, live on TV, twice a week.
INEOS don't interview anybody if they think he's the right guy to begin with. The fact we seemingly couldn't convince/ come to an agreement with those we interviewed is what saved him. They don't waste their time interviewing people that we all know all about, if they don't think they're up to the job. They likely couldn't agree on details like money, the setup, how transfers would be conducted etc. Not because they turned out to be worse candidates.
If I was to guess, they would have been happy with McKenna, Tuchel, De Zerbi, Frank etc, but opted for Tuchel. Hence why McKenna suddenly agreed to stay on at Ipswich. Then Tuchel throws a spanner in the works late on and we've nowhere to turn, so we extend ETHs deal by a year and put out some unconvincing soundbites about us being happy with him, convincing absolutely nobody in the process.
