Manuel Pellegrini has agreed to train Real Betis from next season, with a contract that will run until 2022.
The 66-year-old Chilean coach-led from Manchester City to the Premier League title in 2014.
Betis sacked coach Juan “Ruby” Ferrer last month, after a volatile season, and the team is currently led by interim coach Alexis Trujillo, where the team guaranteed to stay in the league, while he still has four games remaining.
After training in South America, Pellegrini made a leap in European football, when he took over as coach of Villarreal in 2004.
He turned the team into a dangerous competitor, bringing him to the Champions League semi-finals in 2006, and finishing La Liga in second place in 2008.
He also coached Real Madrid, Malaga, West Ham, and Chinese Hebei China Fortune.
