Angel Correa had put Atletico ahead against Getafe in the 18th minute while Costa sent the fans at Wanda Metropolitano Stadium into delirium by scoring the second goal in the 67th, creating a mini-surge as supporters ran down to embrace their returning hero who also played for the club from 2010-2014. Leaving the pitch to celebrate with the fans automatically incurs a booking and, as Costa had already been shown a yellow card for elbowing Djene Dakonam, referee Jose Luis Munuera Montero had no choice but to send him off. Costa, who returned to Atletico from Chelsea for 57m pounds ($77m) in September but could not play until January due to a ban on the club registering new players, will be suspended for Atletico's next Liga game at Eibar. The 29-year-old had scored his first goal in his second spell at Atletico in a 4-0 win at Lleida Esportiu in the King's Cup Wednesday less than six minutes after coming on.

Atletico coach Diego Simeone had no complaint about Costa's sending-off. Sevilla coach Montella, who was sacked by AC Milan in November, got off to a nightmare start in La Liga game as his new team were beaten at home for the first time in any competition since November, 2016. Betis, who scored five goals for the first time ever against Sevilla, struck in the opening minute through Fabian Ruiz. They lost their lead twice before halftime but led 4-2 in the second half through Riza Durmisi and Sergio Leon.
