Karim Benzema's second-half header earned Real Madrid victory over Sevilla as Zinedine Zidane's side maintained their unbeaten start in La Liga.
Real, who lost 3-0 to Paris St-Germain in their Champions League opener on Wednesday, climb to second in the table to ease the pressure on their manager.
Sevilla goalkeeper Tomas Vaclik denied summer signing Eden Hazard a first goal from close-range in the first half.
Meanwhile, the hosts had a late Javier Hernandez goal ruled out for offside.
Sevilla - managed by former Real manager Julen Lopetegui who was sacked after four-and-a-half months in charge in October - fall to fifth following their first defeat of the season.
After their opening win over Celta Vigo, successive draws with Valladolid and Villarreal and a nervy 3-2 win against Levante had made for an unconvincing start to the season for Real.
That feeling was compounded by a heavy defeat to PSG, which left Zidane with a win ratio of below 50% since returning for a second spell as manager towards the end of last season.
Sevilla, with three wins and as many clean sheets from their opening four games, offered a stern test of character and one which, ultimately, Real were able to scrap their way through.
In a game of few clear-cut chances, Vaclik stood strong to deny both Hazard and Dani Carvajal at close-range, while Sevilla failed to land any of their nine shots on target.
The hosts had looked to be edging closer to a goal when Benzema met Carvajal's floated cross with a powerful header after 64 minutes to score his fifth goal of the campaign.
