Swansea's Paul Clement comes up against his former Chelsea boss Jose Mourinho on Sunday admitting that he was once in awe of the Manchester United manager.
Clement was an academy coach at Chelsea during Mourinho's first spell in west London and saw the Portuguese's training-ground methods and "psychology" up close and personal.
