Mauricio Pellegrino has been confirmed as the new Southampton manager on a three-year deal, succeeding the sacked Claude Puel.
The Argentine replaces Claude Puel, who was fired after one season in charge earlier in June.
Pellegrino left Alaves in May after losing the Spanish Cup final to Barcelona and finishing ninth in La Liga.
"My philosophy and the culture of the club will work well," said Pellegrino, who has signed a three-year deal.
"I want to win matches, be successful and develop a team spirit where everyone gives 100% and supports each other.
"I am excited and passionate about what the future holds."
