Getting rid of the last guy is always the easy part. It is the day later, when your mind turns to appointing a successor, that your worries really start. The great problem with managers is that their careers do not proceed with success or failure evident in a linear manner.
The guy sitting joint second in England with a provincial Midlands club was sacked five years ago by Liverpool, who are adrift in sixth, despite having a genuine top tier manager. Davie Moyes reputation was fixed as one of the English game’s tired old options before he got a chance to return to West Ham and has them in a Champions League spot.
Mourinho is the classic example. Champions League winner with two clubs but he presides over the descent of Tottenham. Guardiola needs all the money in the world to keep Man City ahead of Leicester and still awaits a Champions League since parting with his Argentinian Midas. I enjoy watching City but Pep’s eight years there and at Bayern failed to deliver the trophy both clubs wanted.
All you really know about a manager with an impeccable record of improving players and teams is that his form will soon decline; they all do.
Systems bring sustained success in football. Deeply embedded, appropriately resourced and continually reviewed systems: recruitment, development and coaching systems in particular. Get this right and even Klopp would be able to push Liverpool above sixth.
