Southampton have been linked with a double swoop on Porto duo Bruno Martins Indi and Juan Fernando Quintero, according to the Daily Star.
The pair, who would command a sizeable transfer fee should they be allowed to leave Portugal, are said to be in the thoughts of boss Ronald Koeman as he aims for a top four place this season.
A deal for both players would represent a massive coup for the south coast outfit, with Arsenal and Manchester United also linked to the stars.
Martins Indi was linked with Southampton in the summer, having been coached by manager Koeman at their previous club Feyenoord.
Koeman though was unable to attract the Dutch World Cup star to move to England and he joined Porto instead.
Now it seems the 51-year-old has kept his sights on the defender as he looks to add reinforcements at the back as he chases a spot in the Champions league.
Quintero was a member of the Colombia squad that lit up the World Cup finals in Brazil, and although he was kept in the shadow of James Rodriguez, the diminutive midfielder has his fair share of admirers.
Arsenal are another club to show an interest, and the Premier League pair are set to go head-to-head for his signature.
The 21-year-old is still learning the game and that potential has also got both clubs ready to spend at least £16 million.
Champions League attraction
If they hold on to their fourth place finish and qualify for the Champions League next season then any deal for Martins Indi may have to happen this summer.
Quintero might offer a slightly different proposition as Southampton want to take him on loan with a view to buy much like the deals they have with Toby Alderweireld, Ryan Bertrand and Eljero Elia.
That could allow Quintero to see what the Saints are about and if they qualify for the Champions League, he can then join on a permanent basis, a move that would be a huge coup for Ronald Koeman's side if they can get him to the club.
