He has a reputation as one of the best managers in the world when it comes to two-legged ties. They're generally not wrong looking at the record, either.
In 2014/15, Chelsea were unbeaten in the Champions League under Jose Mourinho. It was only that Paris Saint-Germain knocked them out on away goals, following a 2-2 draw, that Mourinho was dumped out of Europe.
