Southampton have completed the signing of Gaston Ramirez from Bologna on a four-year deal.
Ramirez, 21, had been linked with a number of top European clubs, including Inter Milan, Liverpool, Tottenham, but it is Southampton, newly promoted from the Championship, who have won the race for his services.
"A lot of hard work has gone in from the football club with a lot of negotiations behind the scenes to get this deal done," manager Nigel Adkins told the club's official website. "Great credit to everyone because we have a young, exciting talent joining us who is one of the best around.
"The chairman has gone and backed this deal big-time with the financial outlay, and what we have got is one of the most exciting prospects in world football coming to St Mary's. There is a lot of ambition at the football club and we are all delighted that Gastón is going to come and join us."
It is believed the Uruguay international cost Southampton around £12 million.
