Anderlecht's Jordan Lukaku, the younger brother of Chelsea striker Romelu, is reportedly a target for Southampton.
The left-back, who is currently on loan at Oostende, was linked with Tottenham Hotspur last year, but could now join Spurs' Premier League rivals.
Football Direct News quotes a club source as saying that Mauricio Pochettino has looked at Lukaku as a possible replacement for Luke Shaw, who has been linked with a move to Chelsea.
The source apparently told the website: "My understanding is that the boss has been keeping an eye on Jordan Lukaku. The priority is to keep Luke at the club but we have to be realistic and keep replacements in mind just in case."
Like his older brother, Jordan came through the youth ranks at Anderlecht.
