Real Madrid's quest for another La Liga title is humming along nicely, with the club sitting six points clear at the top of the table.
This has come in spite of injuries to key players, with goalkeeper Thibaut Courtois and centre-backs Eder Militao and David Alaba all suffering season-ending injuries early in the campaign.
Notably, all three players are important on the defensive side of the ball for manager Carlo Ancelotti, yet Real Madrid haven't missed a beat when it comes to keeping the ball out of their own net.
Ancelotti's men have allowed a league-best 16 goals through 26 matches, which is half of second-place Girona's tally and 10 goals fewer than the next best defensive sides (four teams).
It's been so hard to score against Real Madrid that they have actually set a club record for fewest goals allowed at this point in a campaign.
Real Madrid have allowed more than a single goal in a league match only two times this season, most recently in a 3-2 victory over Almeria on Jan. 21.
