Real Madrid have let in a solitary goal in six La Liga games. It might be tempting to put this down to a lack of threat from their opposition or the overall effect of Rafa Benítez's emphasis on solidity, but the stats show that Keylor Navas is facing more or less as many shots as Iker Casillas did last time round and Diego López did the season before that.

To date this La Liga season, 'Los Blancos' have allowed an average of 10.16 shots from their opponents per league match, compared to 11.65 last term and 10.86 in the first campaign under Carlo Ancelotti.

The big difference has been the form of their Costa Rican shotstopper, who has been saving Real Madrid's bacon and earning points so consistently that he has been beaten just once from 15 attempts on target. Last season, one of every 3.58 efforts between the posts ended up in Casillas's net (36 goals conceded from 136 goal-bound shots).



Navas is well on course to capture the Zamora Trophy for the La Liga goalkeeper with the best goals-to-game ratio. Tellingly, this accolade has not been won by a Real Madrid keeper since Iker took the prize back in 2008.
