Southampton have signed striker Guido Carrillo from Monaco in a club-record £19m deal.
The 26-year-old Argentine, who scored five goals in 22 appearances for the French side this season, has signed a contract until 2021 at St Mary’s.
“I’m very happy. It’s a great feeling to be a part of this club,” he said.
The deal reunites Carrillo with Southampton boss Mauricio Pellegrino, after previously working with him at Argentine club Estudiantes.
“Lots of things attracted me,” Carrillo added. “I know Southampton from watching the Premier League from when I was small, I’ve always regarded it as the most important league in the world.”
Carrillo scored 20 goals for Monaco after signing from Estudiantes in 2015 and helped the club to the Ligue 1 title last season.
Pellegrino had been expected to reinvest the windfall from Virgil van Dijk’s £75m move to Liverpool and made adding a striker a priority, with top scorer Charlie Austin injured and both Shane Long and Manolo Gabbiadini struggling for goals.
The south-coast club have also been linked with a £30m move for Spartak Moscow winger Quincy Promes.
Southampton vice-chairman Les Reed said: “Guido represents a very exciting addition to our attacking options ahead of the final months of the season.
“We are confident he will benefit us not only in the remainder of this campaign, but in the years to come.”
Southampton’s previous record signing was midfielder Mario Lemina who signed from Juventus in £18.1m deal in August 2017.
On the other hand, Inter Milan and Portugal midfielder Joao Mario has completed his loan move to West Ham.
Manager David Moyes has been keen to add more creativity to his squad, especially after injuries to Manuel Lanzini and Marko Arnautovic.
Mario, 25, signed for Inter from Sporting Lisbon for £35m in August 2016.
But he failed to make the expected impact as he struggled to adjust to the tactical nature of Serie A.
He has not been helped by the Serie A side’s chaotic managerial situation, having sacked two managers last season and replacing a third in the summer, when Luciano Spalletti took over from Stefano Vecchi.
Moyes said he needs Mario to adapt quickly to the demands of the Premier League.
“My biggest concern is not him as a footballer but getting used to the Premier League, the speed and competitiveness compared to Italy or Portugal,” he said.
“His ability as a footballer is not in question, he’s proved it, and I just hope he can hit the ground running. That’s my only concern.”
