AS Monaco striker Guido Carrillo is set to join the Saints in a £19.1m deal, 50% higher than their rebuffed opening offer of £13m.
It’s expected that the 26-year-old striker will sign a five-year deal at St Mary’s.
Carrillo’s 22 appearances this season have mostly come as a substitute as he has been unable to displace Keita Balde, Adama Diakhaby, and Radamel Falcao in the Monaco attack.
With just five goals this season, his is not a prolific profile which will send belief coursing through supporters’ veins that he will improve Southampton’s 24 Premier League goals so far this season.
The Argentinean is not the only striker Saints boss Mauricio Pellegrino is looking to bring in this transfer window.
Spartak Moscow forward Quincy Promes, a 26-year-old Netherlands international, is also interesting the Argentine manager.
Promes has spent three and half seasons in Russia, scoring 58 goals in 115 appearances for his club, as well as scoring four times for his country in 23 appearances.
If the Saints break their record for Carrillo, they can expect to shatter it again with Promes. He signed for Spartak in a reported €15m deal in 2014 from FC Twente of Enschede.
