Karim Benzema hit a hat-trick in the space of 18 second-half minutes as Real Madrid came from 2-0 down on aggregate to stun Paris Saint-Germain and seal a place in the UEFA Champions League quarter-finals on Wednesday.

Kylian Mbappe's jet-heels were propelling Paris on a direct course to the last eight for the first hour in Madrid. The 23-year-old doubled the French side's advantage with his second of the tie and was looking unplayable, with two more efforts chalked off for offside.
