Southampton are pushing to sign Marseille defender Duje Caleta-Car ahead of competition from Aston Villa.
The 25-year-old Croatia international is flying to England this morning with Southampton eager to land a quality centre-back.
They are looking to offload Jan Bednarek with West Ham waiting in the wings for the Poland international.
Southampton had also held talks with Rennes for defender Loic Bade but he is now talking to Nottingham Forest.
Southampton have agreed to loan Jack Stephens to Bournemouth.
Caleta-Car was previously a target for West Ham but turned them down as he waited for a Champions League club.
