Southampton have broken their record for the second time this summer, to bring in Roma striker Pablo Osvaldo for a reported £15m.
The 27-year-old Italy international has long been linked with a move to the Premier League, with Manchester City and Spurs interested.
Southampton have won the battle for Osvaldo's signature, paying an undisclosed fee in excess of the £12.5m they forked out last month for the Celtic midfielder Victor Wanyama.
Osvaldo worked with the Southampton manager, Mauricio Pochettino, at Espanyol, although getting him to the South Coast took some persuasion. The Argentinian forward, though, has now signed a four-year deal at St Mary's, with the fee set to be confirmed to the Italian stock exchange by Roma tomorrow.
The club said: "The frontman is expected to be available for next Saturday's Premier League game against Sunderland at St Mary's, and will be officially presented as a Southampton player tomorrow."
Osvaldo becomes Southampton's latest signing during a summer which has included an £8.5m move for Lyons defender Dejan Lovren and the signing of the Kenyan midfielder Wanyama.
