Inter Milan midfielder Fredy Guarin could end up joining Southampton over Chelsea.
The Colombia international, 27, has been heavily linked with a move to Stamford Bridge, as reported by Simon Jones of the Daily Mail.
But now, it appears possible that Guarin could be offered as a makeweight to allow an Inter Milan move for Southampton striker Dani Pablo Osvaldo, as the Nerazzurri attempt to solve their own striking crisis.
Inter Milan will try once more to prise Pablo Osvaldo away from Southampton, offering Fredy Guarin as part of the deal.
Despite denying interest in Osvaldo the Italians remain keen on the 27-year-old who has struggled to settle after leaving Roma in the summer.
Mourinho is likely to be familiar with Guarin as the player who has played with distinction for two of his former clubs, Porto and Inter, and his versatility as an attacking midfielder or a more central player, not to mention an ability to shoot from distance with both feet, have impressed the Chelsea boss.
He could be of interest to Southampton for these same reasons, and the potential for a move to the South coast shouldn't be sniffed at for a club with big ambitions.
Just last season, goalkeeper Artur Boruc discussed the club qualifying for the Champions League, as per Simon Peach's report in the Daily Mail, while in 2013 they had three players in the England squad for the friendlies against Chile and Germany, as reported by James Orr in the Independent.
After just one win in their last nine league games, Southampton have slipped to ninth in the table, and although manager Mauricio Pochettino claims he is not looking to add to his squad in the January transfer window, as reported by Jacob Steinberg in the Guardian, he may be tempted into doing business if offered Guarin in place of Osvaldo, who has struggled for game time.
Pochettino repeated his desire not to buy or sell in a news conference reported by the club's official Twitter account on Friday.
The Italy international seems to be third-choice behind the established duo of Rickie Lambert and Jay Rodriguez, the club's two top scorers this season with seven and 10 goals.
It is indicative of how highly Inter rate Osvaldo that they are willing to trade in Guarin, a player who has already made 18 Serie A appearances for them this season.
And it may be possible that any move for Guarin to leave Inter hinges on Osvaldo pushing for a return to his home country, something which has not happened yet.
Although Guarin would undoubtedly be attracted to whatever Chelsea can offer him, he is also likely to be impressed by Southampton's progressive thinking on and off the pitch and the offer of regular game time.
