Southampton have broken their club-record fee for the second time this summer after confirming the arrival of Roma striker Pablo Osvaldo in a deal that could be worth up to £14.6million.
After Southampton revealed the Italy international had put pen to paper on a four-year deal, his former employers in the Italian capital released the details on a deal initially worth £12.9m.
That figure could rise by another £1.7m dependent on Osvaldo's performances at St Mary's.
The fee for the 27-year-old, who is due to be presented to the media tomorrow, exceeds the £12.5million they forked out last month to bring midfielder Victor Wanyama from Celtic.
"Southampton football club is delighted to announce the signing of Italy striker Pablo Daniel Osvaldo," a statement on the club's official website, www.saintsfc.co.uk, said.
"Osvaldo today agreed terms on a four-year contract with Saints and moves from Serie A side AS Roma.
"The frontman is expected to be available for next Saturday's Barclays Premier League game against Sunderland at St Mary's, and will be officially presented as a Southampton player tomorrow."
Osvaldo worked with Southampton manager Mauricio Pochettino when the pair were at Espanyol, although getting him to the club took some persuasion.
The Argentina-born forward had been linked with Barclays Premier League rivals Manchester City and Tottenham, before eventually agreeing to commit his long-term future to the Saints.
Osvaldo, who has nine Italy caps, becomes Southampton's third signing of the summer, following an £8.5m move for Lyon defender Dejan Lovren and the signing of Kenya midfielder Wanyama.
Southampton won their opening match of the season at West Brom on Saturday, with a late Rickie Lambert penalty securing a 1-0 victory.
