Clearly and factually it seems he is the brains behind something new at the time being the brains behind a paradigm shift that his aprentices and compariots took to heart and perfected. We are by far the biggest club he managed while rest being second tier with high ambitions, by a mile we are the biggest! In terms of coaching all the prominent apprentices have surpassed him in terms of levels reached. He seem best at building organisation's using small(er) tactically invested funds and upgrading them smartly from what they were and get an edge on the more disorganized similar tiered rivals but never fully hitting the top tier of German football firmly held by Bayern for any long duration.
Expecting someone with this profile, 5-10 some years into retirement from active coaching and for him to come into a club in severe disarray, players already top tier rich, not hungry and dealing with a few grifters, duds and misfires and a few heavily skilled but disgruntled pro players at the same time as trying to school them in on gegenpress, seem a little absurd in hindsight.
The core of his philosophy seem to hinge on players being
A) hungry for a chance, fame and growth while motivated and chased by a similar potential replacement always nibbing their heels
B) an organization behind it all hellbent on growth like Red Bull or smaller but ambitious ownership that back him to the hilt no matter what, operating on full trust.
Taking all that history into account and with the power of hindsight it's all a bit weird how the logic went behind the appointment, particularly in the capacity of coach.
Was he appointed to do a clear out and in the process flush our season? No Manchester united doesnt actively flush a season, a club can just tell the player at the end of the mid/full season, ciao you are not in the plans, no point creating tension mid season. Was he appointed to salvage 4th place? Then why wasn't he given a DM to plug the hole? Was he appointed because we are building an organization in the vein of red bull football? Then why not keep Carrick and mentor him from the side and monitor team progress but not disturb the harmony. More and more it seems like a desperate wishful hail Mary. At this point I hope he at least gets a chance to use this expensively acquired insight and putting it into good use for the future.
