Club career
Early career
Born in Salgueiro, Pernambuco, Santos joined Salgueiro Atlético Clube's youth setup in 2005 after starting out at Escolinha de Futebol do Tête. He made his debut for the former in 2008, appearing rarely in the Série C.
In summer 2010, after a loan stint at Araripina Futebol Clube, Santos moved abroad, joining C.D. Trofense. He made his debut on 29 August, starting and scoring his team's only in a 2–1 Segunda Liga away loss against Gil Vicente FC.
After being rarely used during his first season, Santos appeared regularly during his second, scoring a career-best six goals in 28 matches.
Braga
On 11 July 2012, Santos signed a two-year contract with S.C. Braga, initially being assigned to the reserves also in the second tier. After being an ever-present figure for the latter, he made his first-team – and Primeira Liga – debut on 9 March of the following year, playing the full 90 minutes of a 2–0 home win over C.S. Marítimo.
Santos scored his first goal in the Portuguese top flight on 3 May 2013, his team's second in the 3–2 victory at Moreirense FC. On 25 September he signed a new five-year deal with a €20 million clause, after the Minho side refused an offer from Stade Rennais FC.
Santos was an undisputed starter the following two campaigns, attracting interest from a number of teams, one of them being AS Monaco FC.
Valencia
On 27 August 2015, Santos agreed to a five-year deal with Valencia CF for a fee of €9.5m. His maiden appearance in La Liga occurred on 22 September, as he featured the entire 1–0 away loss against RCD Espanyol.
Santos had subsequent loan spells in his country's Série A, with São Paulo FC and Esporte Clube Vitória.
Later career
On 24 January 2019, Santos joined Al Ahli Saudi FC. On 13 August, he made a return to Portugal on a season-long loan to Rio Ave FC, signing a permanent contract with the latter club the following May.
This brief starts where responsible research should: with the source description of “Aderllan Santos” as brazilian footballer. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as brazilian footballer. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q15830921. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1989, 2005, 2008 and 2010.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
