The Chelsea manager took home €18m last year, putting him well ahead of his peers.
Up in the same pay bracket as Mourinho is the likes of Carlo Ancelotti, the man who replaced Mourinho at Real Madrid, and Bayern Munich manager Pep Guardiola.
Rounding out the top five are two more Premier League managers, Arsenal's Arsene Wenger and Manchester United's Louis van Gaal.
There's a few unusual names in the top 10 too, with Sven Goran Eriksson, Andre Villas-Boas and Fabio Capello all there for their work in China and Russia. It's goes without saying that it's lucrative business.
You might be surprised to see former-Manchester United boss and current Real Sociedad manager David Moyes in the top 20. That's not because the La Liga outfit are paying him an insane amount to coach in Spain, but rather the result of Manchester United's poor judgement in appointing him in the first place.
At least we think so.
Moyes received a fair chunk of change as part of his pay off from the Old Trafford club, and it's likely that this was taken into account when calculating his earnings.
He was sacked after just 10 months in charge, and considering he still had the vast majority of his six-year contract remaining, United were forced to bite the bullet and give him a huge fee just to let him go.

1. Jose Mourinho (Chelsea) €18m
2. Carlo Ancelotti (Real Madrid) €15.5m
