Maybe on reflection PSG were done for the moment it appeared that Kylian Mbappe was not going to be fit enough to play. Take the flying French forward out of Mauricio Pochettino's team and they simply cannot play the same way.
Mbappe leads the PSG charge. He scares defenders and in his wake there opens space for others.
We saw that in Paris last week as the French champions threatened to take the tie away from Manchester City in the first half and the absence of that threat was notable at the Etihad Stadium on Tuesday night.
