After a mixed three-year spell in charge of Real Madrid and a series of clashes with his strikers this season, does Tuesday night's win prove the Portuguese is back to his best?POLL
It has been a mixed few years by the lofty standards of Jose Mourinho. He left Spain under a cloud having run his Real Madrid squad into the ground in the pursuit of Barcelona, and returned to Chelsea last summer having rebranded himself as 'the Happy One'.
It's not been the perfect season at Stamford Bridge either, and he attracted criticism last week when he hit out at his strikers yet again following the Blues' 3-1 defeat in Paris.
But on Tuesday night one of those strikers, Demba Ba, became the hero as he got the vital second goal in a 2-0 win which sends Mourinho's men into the Champions League semi-finals. It will be his eighth appearance at that stage in 10 seasons.
So is Mourinho back?
What do you think? Is the Special One back in the groove? Has he still got something to prove? Did he never go away?
