Real Madrid Keeper matches Casillas' total from 2010/11

Keylor Navas kept a clean sheet in Real Madrid's 1-0 win over Real Sociedad at the Estadio de Anoeta on Saturday, bringing his total for the season to 20.

Iker Casillas achieved the same number of clean sheets five years ago, in a season where injury forced him to spend a lot of time on the sidelines.

Navas has two more league games, a Champions League semi-final to play - and potentially a final - to add to his tally.

The Los Blancos number one was almost sold at the start of the season, but he stayed and went on to break the club's record for consecutive clean sheets.

The previous record had been set in the 1975/1976 season.

Naval was a safe pair of hands again in Saturday's win in the Basque country, and the Costa Rican was only really called into action at the death.

He puts a lot of trust in the four defenders in front of him, and the five-man defensive unit will have to maintain their level if Real are to go on and win La Liga and the Champions League.
