Chelsea, uncharacteristically for a Jose Mourinho team, produced some pretty shambolic defending for Edinson Cavani’s goal in their CL clash on 17th February, 2015. Cavani’s goal v Chelsea was an equaliser for PSG after Branislav Ivanovic had put Chelsea ahead.
The poor defending prompted a rather funny pic to make the rounds of the internet
Here’s that pic and a video of the Cavani goal and Chelsea’s poor positioning (Video of Cavani at 1:06 mark)
