Having joined from Benfica last September, Dias’ new deal will keep him at the Club through until the summer of 2027.
The 24-year-old arrived at the Etihad Stadium from Benfica during last summer’s transfer window and made an instant impact with his defensive acumen, technical quality and winning mentality all proving key ingredients in a magnificent debut season for City.
He went on to make 50 appearances in all competitions, scoring once as Pep Guardiola’s side lifted both the Premier League title and retained the Carabao Cup as well as reaching a first-ever Champions League final.
Dias’ individual importance was also recognised with the Portuguese international winning the prestigious Football Writer’s Association Footballer of the Year award.
In addition, Dias was voted both the Premier League Player of the Season and the Etihad Player of the Season and last week he also was announced as the 2020/21 UEFA Champions League Defender of the Season.
“I’m very happy to sign the new deal,” Dias said. “I have enjoyed every single minute of my time at City since joining last year.
“Playing for City has surpassed all my expectations and it’s an absolute pleasure to be part of such an incredible squad.
“I would also like to thank Pep and the coaching staff for the way they have helped me to develop as a player and keep pushing me to improve.
“To be part of the squad that achieved so much last season was incredible and made us all hungry to achieve even more.
“Now I just want to try and play my part in helping us be successful this season and beyond.”
Director of Football Txiki Begiristain added: “Ruben’s new deal is great news for our Club.
“Although he only joined us less than a year ago, in that time Ruben has already proved to be such a vital part of our squad.
“And it tells you everything about his quality and importance to the Club that we wanted to recognise his impact with this new contract.
“He is everything you would want in a central defender and so much more and he will be a big part of our drive to bring even more success to the Club over the next few years.”
Everyone at Manchester City congratulates Ruben on his new contract and wishes him the best of luck for the rest of his career here.
