Yan Matheus Santos Souza (born 4 September 1998), known as Yan Matheus or just Yan, is a Brazilian professional footballer who plays as a winger for Qatar Stars League club Qatar.
Yan was born in Alagoinhas, Bahia, and joined Vitória's youth setup in 2009, aged 11. He made his first team debut on 31 October 2015, coming on as a second-half substitute for Vander in a 3âÂÂ2 Série B home loss to Náutico; he also assisted Rafaelson's second goal.
Yan featured in two more matches for the club during the campaign, as they achieved promotion to the Série A. He made his top tier debut on 30 June 2016, replacing Dagoberto late into a 3âÂÂ2 home win over Sport Recife.
In January 2017, Vitória agreed to loan Yan to Palmeiras, as a part of the deal which saw Cleiton Xavier move in the opposite direction; the loan move only became official in April. In April 2018, he signed a permanent deal with Verdão after the club exercised his buyout clause.
On 31 January 2019, after making no first-team appearances for Palmeiras, Yan was loaned to LigaPro side Estoril until the end of the season. He made his debut for the club on 17 February, in a 1âÂÂ1 away draw against Mafra.
Yan scored his first professional goal on 31 March 2019, but in a 3âÂÂ1 home loss to Benfica B. He scored a further goal in 13 appearances for Estoril, as they missed out promotion after finishing third.
On 10 June 2019, Yan moved on loan to Sport Recife until the end of the year. After featuring regularly, his loan was renewed for a further year on 6 December, but Palmeiras recalled him on 13 July 2020.
On 16 August 2020, Yan returned to Portugal and joined Moreirense in the Primeira Liga on a three-year loan deal. A regular starter, he scored six goals during the 2021âÂÂ22 season but was unable to avoid the club's relegation.
In July 2022, Moreirense bought 50% of Yan's economic rights.
