Thibaut Courtois became the saviour of Real Madrid at the start of the match. The Real Madrid goalkeeper stopped a close-range header from Tonny Sanabria from the edge of the six-yard box.
The move started with a great cross from the left by Sergio Canales who put the ball right on the Paraguayan forward's head.
Sanabria, who is making his debut as a starter in the 2020-21 season, came up against a Courtois who was determined to keep a clean sheet.
When everything seemed set for Betis to score, the Real Madrid goalkeeper pulled off an incredible save to prevent the Andalusian side's goal.
