Sergio Ramos was Real Madrid's penalty hero for the second time in four days as a 1-0 win at Athletic Bilbao sent the LaLiga leaders seven points clear.
Zinedine Zidane's men have been flawless since the season's restart to claim control of the title rice, but they were given a stern test by Getafe on Thursday and again had their work cut out for a time on Sunday.
Yet as against Getafe, Ramos stepped up to net a second-half penalty and secure all three points in Bilbao, with his latest decisive goal coming after Dani Garcia tripped Marcelo in the area to prompt a VAR review.
A seventh straight victory ensured Madrid made the most of playing before rivals Barcelona, who will kick-off at Villarreal later in the day knowing they have an even more significant gap to make up.
Madrid recalled Marco Asensio for his first start of the season in a move which almost brought immediate reward.
The fit-again forward drew a low save from a fourth-minute free-kick, with Karim Benzema then unable to direct his header goalwards when Dani Carvajal squared the rebound.
That was about the extent of Athletic goalkeeper Unai Simon's involvement before half-time, while Thibaut Courtois repelled Raul Garcia's powerful header at the other end.
Simon might have had a far greater role to play, though, as both Rodrygo and Benzema squandered huge headed opportunities from searching Asensio centres, each missing the target completely.
The second period appeared set to play out in similarly frustrating fashion for Madrid until Marcelo went down in the area and a penalty was eventually awarded, with Ramos coolly tucking his finish inside the left-hand post in the 73rd minute.
Simon saved smartly with his legs from Benzema in the closing stages, but the one Ramos goal proved enough for Madrid again.
