Jose Mourinho feels his way of working changed football and there is a clear distinction between before and after his emergence.
The iconic boss first came to the world’s attention when he won the Champions League with Porto in 2004, earning a move to the Premier League with Chelsea.
In his first of two spells with the Blues he won the Premier League twice, before leaving for Inter Milan where he won two Serie A titles and the Champions League in 2010.
