Born in Gafanha da Nazaré, Aveiro District, Dias played youth football with four clubs, including A.D. Sanjoanense from ages 12–17. He finished his formation with S.C. Braga and, on 9 August 2014, played his first game as a professional with their reserves, coming on as a late substitute in a 0–1 away loss against C.D. Tondela for the Segunda Liga championship.
Dias signed with AS Monaco FC in January 2015, going on to appear mostly for the reserve team during his tenure. On 6 January 2016, he was loaned out to Portuguese second division side Varzim S.C. until the end of the season.
For the 2016–17 campaign, still owned by Monaco, Dias joined Rio Ave FC. He made his Primeira Liga debut on 12 August 2016 in a 1–3 home loss against FC Porto, and scored his first goal in the competition on 18 September to help the hosts defeat Sporting CP 3–1.
Returned to Monaco, Dias made his first appearance in Ligue 1 on 13 August 2017 when he featured the last minutes of the 4–1 away win over Dijon FCO. Two days later, he moved to Serie A club ACF Fiorentina on a two-year loan deal with obligation to buy at the end of the term.
