Barcelona new coach 2019
You're referring to the appointment of Ernesto Valverde's successor as the head coach of FC Barcelona in 2019!
After Ernesto Valverde was sacked in January 2019, Barcelona appointed Quique Setién as their new head coach. Setién, a Spanish football manager, was previously in charge of Real Betis and had a successful stint with the club, leading them to a 7th-place finish in La Liga and a Copa del Rey semifinal appearance.
Setién was appointed as Barcelona's new coach on January 13, 2019, and he signed a contract until June 2022. During his tenure, he led the team to a 22-match unbeaten run in all competitions, including a 5-0 thrashing of Real Madrid in El Clásico.
However, Setién's time at Barcelona was cut short due to the team's poor performance in the 2019-20 season, which saw them finish 8th in La Liga and exit the Champions League in the quarterfinals. On August 21, 2020, Barcelona announced that Setién had been relieved of his duties as head coach, and Ronald Koeman was appointed as his successor.
