"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."Argentine Mauricio Pochettino may be best remembered by football fans as the defender who fouled Michael Owen at the 2002 World Cup to give England a penalty - which was scored by David Beckham.

He will now take control of Southampton's training session on Saturday and will be in charge for his first game on Monday night against Everton. Pochettino said:
"This is the kind of opportunity that any coach would relish. Southampton is a club with great heritage, and an even more exciting future. "There is a clear vision to take the club to a new era of sustained success in the Premier League, and beyond, which I'm delighted to be part of."
