The former Spain midfielder, who looks set to lead Leverkusen to the Bundesliga title, was a reported target for Liverpool and Bayern Munich - two of the clubs he played for.
When the analysis was first done, Alonso - who was still in the running - was only ranked fifth out of the six potential candidates. We list the candidates in order of their suitability according to Carteret's analysis, based on a number of key metrics to give an objective sense of the strengths and weaknesses for each head coach.
He previously shared the same agent as Klopp - Marc Kosicke - and was described by the current Liverpool manager as a "young horse" and a "big, big coaching talent", with Carteret giving him the highest strategic intelligence rating of anyone. The former Chelsea boss, who led Bayern to the title last season, was also found to have "a very similar defensive style of play as Nagelsmann, and that could prove to be a challenge for Liverpool supporters and for maximising the attacking coefficients of the current Liverpool players".Carteret found some strong similarities between Postecoglou, 58, and Klopp - with strategic intelligence, tactical command, and shot creation ratio broadly equivalent , as is overall possession.
