Saints debut: Watford (H) 13/08/2016
Former clubs: Olympique Lyonnais, FC Metz (loan), OGC Nice, FC Guingamp (loan).
Well known to Saints manager Claude Puel, 27 year-old Pied previously worked with Puel at two of his former clubs.
The right sided defender, who can also play further forward if required, has played his entire career to-date in France having started out at top-flight side Lyon and making a loan move to Metz before joining OGC Nice in 2012.
It was at Lyon that he first encountered Puel, having come through the ranks at Les Gones where he came through alongside the likes of Alexandre Lacazette and Samuel Umtiti.
During this time, Pied made appearances for France at each youth level up to the Under-21 side, while he would also pick up his first silverware soon after when Lyon landed the Coupe de France in 2012.
After three years together in the senior side, where highlights included helping the club reached the semi-finals of the Champions League for the first time in its history, Pied followed his manager to Nice.
They spent a season apart when Pied went out on loan for the duration of the 2014/15 campaign to En Avant de Guingamp where he was a regular in the side that reached the round of 32 in that season’s Europa League.
They also reached the semi-finals of the Coupe de France, but Guingamp finished mid-table in the league with a tenth placed finish.
Follows Puel to Nice
Upon his return to OGC Nice last season Pied helped Puel’s side achieve qualification to the Europa League group stage thanks to a fourth place finish in Ligue 1.
Nice kept 13 clean sheets last season with Pied in the side, the fifth meanest defence in the division.
They secured fourth on the final day of last season with a 3-2 win over Guingamp in which Pied played the full 90 minutes at right back.
He now follows Puel for a third time to join Southampton where he has become the first Frenchman to sign for the club following Saints’ return to the Premier League in 2012.
