Jude Bellingham completed a £115 move from Borrusia Dortmund to Real Madrid in June this year.
The English international rejected a move to the premiership to test his might at the highest stage at Spain.
Madrid faced Sevilla in a bid to make it 11 out of 11.
Bellingham pounced on a loose ball behind Sevilla’s box and drive home to make it 1-0 for Carlo Ancelloti’s side.
He scored his 11th goal as he waves his hands to adore the supporters.
His celebration was cut short as the referee whistled for a foul during the build-up.
