Sergio Ramos scored a late penalty as La Liga champions Real Madrid came from behind to scrape a 3-2 win against 10-man Real Betis. Betis were ahead at half-time after two goals in two minutes from Aissa Mandi and William Carvalho overturned Fede Valverde's opener. But Betis defender Emerson, on loan from Barcelona, endured a nightmare start to the second half by scoring an own-goal and then being sent off for knocking over Luka Jovic after the striker had been sent clear. VAR again intervened in Madrid's favour in the 82nd minute as Marc Bartra was adjudged to have cleared with his arm, leaving Ramos to chip in the winning penalty. Betis were fuming at referee Ricard de Burgos at full-time and while the red card seemed fair, they were unlucky to concede the penalty, with Bartra seemingly nudged into the ball by Madrid's Borja Mayoral. Madrid, though, breathed a sigh of relief, their opening win secured having kicked off the season with a goalless draw away at Real Sociedad last weekend. "I'm not getting into the referees," said Zidane. "We suffered of course but in the end we got the three points." This was an uncharacteristically sloppy defensive display from Zinedine Zidane's side. It was the first time they had conceded twice in the first half of a league match since Zidane returned as coach 18 months ago and it would have cost them had their opponents been less generous. Defeat for Betis ends what had been a perfect start under new coach Manuel Pellegrini, after two wins out of two against Alaves and Real Valladolid. "From Madrid's first goal to the end of the first half we were much superior," said Mandi. "But we weren't able to get a clean sheet in the second half."
