WATCH: Kylian Mbappe makes the breakthrough as Real Madrid lead Leganes

Real Madrid know they can close the gap on Barcelona at the top of La Liga to four points (also with a game in hand) if they can beat Leganes in an all-Madrid affair. So far they are on course to do so, having taken the lead at Butarque.

Carlo Ancelotti's side dominated the first half and with just a few minutes to go until the break, they broke the deadlock thanks to Kylian Mbappé.
