Executive Chairman, Nicola Cortese said:
“This decision has been made with the long-term ambitions of Southampton Football Club in mind. Whilst we acknowledge the contribution Nigel has made during the past two years, for the Club to progress and achieve our long-term targets a change was needed.
“Mauricio is a well-respected coach of substantial quality who has gained a reputation as an astute tactician and excellent man manager. I have every confidence that he will inspire our talented squad of players to perform at the highest possible level."
