Real Madrid will be looking to kick-start their Champions League campaign against Club Brugge on Tuesday after losing to Paris Saint-Germain on matchday one, while Kylian Mbappe has his eye on a record of Lionel Messi's.
Madrid were crushed 3-0 by PSG last time out, with Thomas Tuchel's men looking extremely comfortable in a match that left Zinedine Zidane under a bit of pressure.
They have since bounced back with two wins and a draw in LaLiga and they will expect to get three points at home to Club Brugge, while PSG travel to Galatasaray.
The French champions will be able to call upon the services of Mbappe this time, having missed the Madrid clash through injury, and he is close to equalling a record set by Messi.
Below, we have highlighted the key data ahead of Tuesday's contests.
