Mourinho's recent sour demeanour at Manchester United makes it easy to forget that he is one of the most successful managers in recent history. Having begun his managerial journey in Portugal, Mourinho has managed in some of the biggest leagues around Europe, sweeping titles at almost every club he has managed.
His phenomenal managerial record is evident by his win percentages since taking over as Porto manager. The Portuguese's win rate has dipped below 60% at only one club during this time - his second spell at Chelsea. Besides that, he has enjoyed win ratios of more than 70% at both Porto and Real Madrid.
Mourinho's time at Manchester United has been heavily criticised in the media as he failed to win the Premier League for two consecutive seasons. However, the 55-year-old did win the Europa League and EFL Cup during his first season at Old Trafford and boasts an excellent win percentage of 61.7% over the past two years.
While his methods may not appeal to all tastes, Mourinho certainly knows how to win as is proved by his trophy haul and overall career win percentage. He will surely be determined to avoid the so-called "third-season syndrome" this year and buck his managerial trend by bringing further success to Old Trafford and enhancing his already excellent statistics.
