Southampton have announced midfielder Oriol Romeu has signed a new four-and-a-half-year contract with the club.
The 25-year-old Spaniard joined from Chelsea in the summer of 2015 and has made 50 Premier League appearances for Saints to date.
Speaking about his new deal to 2021, Romeu told Southampton's official website: "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.''
Southampton 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.''
