''Mourinho the Special One Does it Again''

There it was again. The manic touchline run. It was how we were introduced to Jose Mourinho, a decade ago, and how we will remember him after he is gone, too.

Cesar Azpilicueta shot, the ball caught a tiny hold-up deflection and fell to substitute Demba Ba. It wasn't, fair to say, the cleanest finish.

 Ba almost scooped it into the roof of the net, off his boot, off his shin, somehow looping over goalkeeper Salvatore Sirigu. No-one cared.

Chelsea were through, and off went Mourinho, down the line to join the celebrations by the corner flag, just as he had done when Porto equalised at Old Trafford to eliminate Manchester United in the same competition in 2004. 

This, like that, was one of his greatest nights. Chelsea have come back from 3-1 down before in the Champions League, but not at this late stage and not against a team with the potential of Paris Saint-Germain.
