Ronald Koeman is hoping to sign Ryan Bertrand on a permanent transfer from Chelsea in January.
The left-back moved on loan to St. Mary's this summer as a replacement for the departed Luke Shaw and has done a stellar job since arriving.
His natural pace and attacking instincts have caught the eye, but he has also been solid defensively and Koeman has clearly been impressed by the English youngster.
The Dutchman is now hoping to tie Bertrand down to a permanent deal and suggests that his development would be better served by staying on the South-Coast.
Koeman says that Bertrand needs to be playing regular first-team football at his age and, whilst he is one of the Saints' key players, he would have to play a back-up role at Chelsea.
"If we have the money, yes [I would like to sign him]," Koeman is quoted as saying by the Daily Mail. "If its up to me, yes."
"Maybe it's too early to talk about that, but I am very happy until now with the performance of Ryan."
"Ryan got the opportunity (at Southampton) to play every weekend what he missed in Chelsea, he’s still a young player and the best way to develop yourself is playing every weekend."
If Bertrand does return to Chelsea then he will have to compete with Felipe Luis and Cesar Azpilicueta for a place in the line-up and his chances of displacing either look slim.
It means that Southampton may be the best possible venue for him, especially as his style of play seems perfectly suited to the team.
The Saints like to play swift, attacking football and Bertrand has fitted in superbly since joining.
Koeman's side have been one of the surprise packages in the Premier League so far and they will be looking to keep their fine form going when they face Stoke City at the weekend.
