Who were the better coaches?
But from what I remember reading, the most experienced candidate for the role was Ernesto Valverde but he wasn't interested in a role as the place holder for 6 months, according to reports. So it came down to Rudy Garcia and Ralf Rangnick and the temporary role was given to Rangnick.
But for me it doesn't matter who was selected because the damage was already done by Solskjaer, Phelan, Wells and Woodward/Judge in a board - manager led football structure. And to make matters worse we also lost 3 of our prominent first team coaches in McKenna, Carrick and Pert and things became even more unstable. It's extremely difficult to recover in such circumstances.
I don't believe I ever got the impression the club brought Rangnick in to restructure the football side of the club. He was brought in to concentrate on the first team until the end of the season, which is something Rangnick has repeatedly confirmed in press conferences. Rangnick himself confirmed in his first press conference that he took the job because managing Manchester United was something he couldn't turn down. And when asked about the consultancy role, he said that 'you have to ask the club about that'
I've already mentioned this several times in the past 5 or 6 months, and that is that United have signed up-to the consultancy firm setup by Rangnick and Lars Kornetka. And the only journalist who has even spoken about it is Rory Smith who currently works for the New York Times and formerly of the Times UK. The link for the site in question is below.
