Kylian Mbappe scored an injury-time winner as Paris Saint-Germain warmed up for their Champions League showdown with Real Madrid by beating Rennes 1-0 in 
Ligue 1 on Friday. 

Mbappe fired home from a Lionel Messi assist in the third minute of added time at the Parc des Princes having earlier seen a deflected strike come back off the post and been denied a goal by the tightest of offside calls.
