Benfica B

Dias started his career at local club Estrela da Amadora after being brought to the club by a close family member. Dias initially played as a striker, before switching to defence, due to his team being losing by two goals during a match. He moved to Benfica's youth academy in 2008, where he played initially as a midfielder, before changing position to centre-back for the junior side until 2015. In the same year, on 30 September, he made his professional debut with Benfica B in a 2015–16 LigaPro match against Chaves. On 7 March 2016, Rui Vitória called 18-year-old Dias for Benfica's UEFA Champions League Round of 16-second leg tie against Zenit Saint Petersburg after three of his four main centre-backs were unable to make the trip to Russia. The following season he helped the B team finish fourth; the club's highest ever position obtained in the second division. He also helped the junior team reach the final of the 2016–17 UEFA Youth League.
