The 20 best coaches in world football

A Spanish think-tank has published a list of the top 20 coaches in world football.

The Coach Reputation Ranking analysed "100 variables from 10 categories in coaching," including experience, trophies won, win percentage, leadership qualities, and reputation.

It has also considered the "evaluations" of people well-placed in the industry, such as sports directors and journalists.

Manchester United manager José Mourinho and Manchester City boss Pep Guardiola feature, but there are some surprises - including two coaches who have not won a single title.
