Romeu, who arrived at St Mary’s ahead of the 2015/16 campaign, has extended his stay until 2021 following an excellent season so far under Claude Puel.



The former Barcelona player made 35 appearances during his first season at St Mary’s, scoring goals against Aston Villa and Crystal Palace.



This season, Romeu has missed just one Premier League game since the start of the campaign, featuring on 30 occasions in all competitions under Puel.



Fans voted the midfielder as the club’s Under Armour Player of the Month in both September and October, following an excellent start to the campaign for the Spaniard.



Speaking about his new contract, Romeu said: “I couldn’t be any happier to have this new contract with the club.



“Ever since I came here I have felt very, very good. Everything has been positive for me. I have developed myself and been getting better every day.



“Looking forward, it’s a good thing for me, but hopefully there will be more to come and nice experiences to go through.”

Executive Director of Football Les Reed added: “We’re delighted that Oriol has extended his commitment to Southampton Football Club.



“We’re confident he will continue to build on what has been an impressive 18 months since he joined us from Chelsea.



“Since arriving at the club, Oriol has worked extremely hard to establish himself as an integral part of the team and we firmly believe he will continue to be a key pillar in our squad for many years to come.



“At the age of 25, Oriol still has the capacity to develop and progress as an individual, and we’re very pleased that he sees Southampton as the perfect environment for him to do just that.”
