Chelsea have a mountain to climb if they’re to go through to the quarters of the Champions League.

The Blues lost by three goals to one against Napoli in Italy.

Juan Mata put Chelsea in front but the Neapolitans fired a three goal salvo which gives them the advantage going to Stamford Bridge in three weeks time.   

In the other match CSKA Moscow snatched an equaliser three minutes into injury time to draw 1-1 at home to Real Madrid.
