His reckless mistake in the first half ultimately proved decisive as the visitors were never able to recover from their deficit, succumbing to a third defeat in just eight games this season.For reasons best known to him, the German came rushing out of his box in a moment of absolute madness and was nutmegged by Carrasco. The Belgian then nonchalantly slotted into an empty net from outside of the box.Marc-Andre ter Stegen has now made five errors leading to goals since April 2019, more than any other player in LaLiga in that timeframe.What was he thinking?! pic.twitter.com/PIrUo1SNLT— Squawka Football (@Squawka) November 21, 2020The moment was quite reminiscent of his compatriot Manuel Neuer's blunder against South Korea at the 2018 World Cup. Even though Ter Stegen is capable of the sweeping style sometimes, this was one occasion where he paid the price.Hit: Yannick Carrasco (Atletico Madrid)Carrasco attempted the most dribbles in the match (5), just one more than Lionel MessiYannick Carrasco was in full motion when Ter Stegen came rushing to him, but he instantly nudged the ball through the keeper's legs before rifling a shot into the empty net from about 30 yards out.Yannick Carrasco (2) has now scored more open-play goals in LaLiga this season than Lionel Messi (1).— Squawka Football (@Squawka) November 21, 2020It was clinical stuff from the Belgian, who was a bag of tricks in the match, showing off some nimble footwork to bamboozle his markers while also testing the visitors with his direct runs.In fact, the 27-year old attempted the most dribbles in the match (5), just one more than Lionel Messi, and completed four. He was at the heart of Atletico Madrid's offensive game against Barcelona.
