Tactics expert Michael Cox speaking on BBC Radio 5 live:
"It's been an intriguing game, a strangely poor performance from Chelsea so far - no real passing or flow to their game. There is no real urgency from Chelsea, they have sat very deep and they are quite lucky to be 1-0 up at this point.
"The golden rule for PSG should be to never let the ball bounce and Andre Schurrle's finish was fantastic as a result. We spoke about Edinson Cavani before the game how he was playing in his favoured role and the same can be said of Schurrle - he is probably Chelsea's main bright spark during this game and now has a great chance after Eden Hazard's injury."
