Jude Bellingham’s injury time winner was enough to secure all three points against Getafe, after reopening their Satiago Bernabeu home.
It is now a spectacular space-age arena, complete with a retractable roof, which remained closed for Saturday’s curtain-raising visit of Getafe amid autumnal storms.
Bellingham has been on fire since he came to Real Madrid from Germany.
He scored on his debut at Athletic Bilbao, added two more in a victory at Almeria, and then netted a late winner at Celta Vigo to secure three straight away wins.
After the opening day win in Bilbao, manager Carlo Ancelotti said: “He has a lot of personality and has adapted very quickly. It already seems like he’s been with us for a long time.”
Bellingham was named La Liga’s player of the month for August, setting the stage for his home debut at the Bernabeu’s elegant reopening.
Getafe striker Borja Mayoral intercepted a poor pass from another Real home debutant, left-back Fran Garcia, to get past goalkeeper Kepa Arrizabalaga and convert an early opener for the visitors.
Bellingham is the third player in Real Madrid history to score in each of his first four games for the club – following Pepillo in 1960 and Cristiano Ronaldo in 2009.
