In-demand Benfica centre-back Ruben Dias has agreed a contract extension that will keep him at the club until 2024.
The 22-year-old joined the Eagles academy in 2008, before making his debut nine years later. He quickly became an integral member of the side, making 85 appearances across his first two campaigns at senior level. Dias was a standout figure in both seasons, with his immaculate form catching the eyes of Manchester City and Tottenham Hotspur.
The Sky Blues are weighing up a bid for the Portugal international in January after it became clear Pep Guardiola required defensive reinforcements, while Spurs boss Jose Mourinho has asked Dias' agent to keep him updated on the player's situation at Benfica.
The Eagles confirmed the youngster had agreed terms on a new deal via their official website, with their announcement revealing the contract includes a release clause of €100m.
Discussing his decision to sign on for five more years, Dias explained: "I’ve always been calm over this time. My mind was always where it should be. Me and the club were in line and we have reached this deal in time.
"There's only one thing in my head: to win and bring titles home. I believe that this was the main reason for the renewal."
Dias was included in the starting lineup for the Lisbon outfit's 2-2 draw at RB Leipzig on Wednesday, a game in which they surrendered a two-goal lead in stoppage-time.
The result leaves them on the brink of a group stage exit in the Champions League after Bruno Lage's recruits collected just four points from their opening five pool fixtures.
Benfica's struggles in Europe could mean City still have a chance of bringing Dias to the Etihad Stadium this winter. it's likely the defender will want to keep competing at the highest level, which the Sky Blues can offer following their qualification for the last 16.
His release clause is staggering, but it's not beyond the Premier League champions' financial capabilities. If they genuinely want him to join in January, they will have no issue in signing him. There will be no tricky negotiations, all they must do is pay the requisite fee.
