Love him or loathe him, it's hard to find fault with José Mourinho's managerial record. The 54-year-old Portuguese coach has won everything you can as a manager – multiple times.
He's won the Champions League twice, the UEFA Cup and the Europa League as well as a number of titles in Portugal, England, Italy and Spain.
He may not play the most attractive brand of football but he knows how to win, and in a results driven business that's what matters most. That's one criticism he has a retort for. However, it's the development of players, or lack of, under his management which has plagued him throughout his career.
With very good reason, too. While at Chelsea he sold Kevin de Bruyne – now pulling the strings at Manchester City, Romelu Lukaku – goalscorer supreme for Everton, Juan Cuadrado – an Arsenal transfer target, and Liverpool new-boy Mohamed Salah. All weren't given a fair opportunity under Mourinho but the quartet flourished elsewhere and have been exchanged for eye-watering amounts of money over recent seasons.
We've taken a look at how the four players fared pre, during and post the Portuguese manager.
