Marquinhos

Corinthians

Marquinhos joined Corinthians at the age of eight in 2002. After winning the state junior cup, he was first included in a senior matchday squad on 29 January 2012, remaining an unused substitute in their 1–0 home win over Linense in the Campeonato Paulista. He made his professional debut in the competition on 18 February, playing the full 90 minutes of a victory by the same score at São Caetano. He made eight appearances across the season, as the Timão topped the table in the regular season but were defeated by Ponte Preta in the play-offs quarter-finals. After the conclusion of the state championship, Marquinhos made his Campeonato Brasileiro Série A debut on 20 May 2012, playing the full 90 minutes in a 0–1 loss to Fluminense at the Paulo Machado de Carvalho Stadium; both teams were resting players in the first game of the season due to concentration on the Copa Libertadores. He played six games in the national championship, and was an unused substitute as the club won the 2012 Copa Libertadores Finals against Boca Juniors.

Roma

In July 2012, Marquinhos was signed by Italian club Roma from Corinthians. The transfer was initially a one-year loan for a fee of €1.5 million, rising to €3 million after he made eight first-team appearances of at least 45 minutes each. At Roma, he played under the name "Marcos" printed on his jersey to avoid confusion with teammate Marquinho. Marquinhos made his debut on 16 September in a 2–3 loss against Bologna at…

Youth and first caps

Marquinhos played every minute of Brazil's campaign at the 2011 South American Under-17 Football Championship, as they won and qualified for that year's World Cup in that category. He was again an undisputed starter except for one match at that tournament, as the team took fourth place in Mexico. In October 2013, Marquinhos, who is of dual Portuguese and Brazilian nationality, stated that he would be open to representing the Portugal national team. However, later that month, he received his first call-up for Brazil when Luiz Felipe Scolari named his squad for friendly matches against Honduras and Chile to be played that November. He made his debut against Honduras in Miami on 16 November, replacing David Luiz for the last 20 minutes of a 5–0 win. Marquinhos played for Brazil Under-21 at the 2014 Toulon Tournament, featuring in all five of their matches as the country won the tournament. He scored to put Brazil 3–2 up in their eventual 5–2 win in the final over France.

2016: Olympic gold and Copa América Centenario

After missing the 2014 FIFA World Cup on home soil, Marquinhos returned to the senior side in September 2014 under new manager Dunga. He featured in friendly wins over Colombia and Ecuador in Miami, making his first start against the latter. Marquinhos was included in the Brazilian squad for the 2015 Copa América in Chile, his first major international tournament. He made his competitive debut – and only appearance in the…

In terms of his playing position, Marquinhos is predominantly deployed as a central defender, but has also been used at right-back and in a central or defensive midfield role. He is noted for his anticipation, pace, and intelligence, as well as his technical skills, composure, passing ability, elegance on the ball, and confidence in possession, which enables him to break down attacks and subsequently play the ball out or start offensive plays from the back. On signing for Roma, Marquinhos described himself as a quick player, with a good positional sense, who wins back a lot of balls, and who can impose himself on a game due to his ability to start attacking plays from the back. He named Thiago Silva as his role model. In March 2015, Marquinhos told FourFourTwo that he compensated for his average height for a defender by honing his strength and timing, attributes he learnt from PSG assistant manager Claude Makélélé. He praised manager Laurent Blanc, a former defender himself, for encouraging the PSG defenders to attack in set pieces and teaching them the correct positioning in that situation. Fellow Roma defender Nicolás Burdisso said in August 2012 that Marquinhos was "a little phenomenon. He has speed, heading ability, he knows what to do, he is humble. He is a little Thiago Silva". In January 2014, Marquinhos was named by British newspaper The Observer as one of the ten most promising young players in Europe. They wrote, "He has the temperament to remain undaunted, the…

São Paulo

Marquinhos made his professional debut for São Paulo on 11 July 2021, coming on as a 78th minute substitute in a 1–0 Série A home win against Bahia.

Arsenal

On 13 June 2022, Marquinhos signed for English club Arsenal on a long-term contract. However, fellow Premier League side Wolverhampton Wanderers were considering taking legal action against both Marquinhos and São Paulo, as Marquinhos had reportedly signed a pre-contract agreement with them prior to joining Arsenal. On 8 September, Marquinhos made his competitive debut for Arsenal in a 2–1 UEFA Europa League away win over Zürich, where he scored his first goal both for the club and in European competition, and also registered an assist for Eddie Nketiah in the same match. He made his Premier League debut on 18 September, coming on as a late substitute for Bukayo Saka in a 3–0 win at Brentford. His first appearance at the Emirates Stadium came on 6 October, in the Europa League game against Bodø/Glimt.

Loan to Norwich City

On 31 January 2023, Marquinhos joined Championship club Norwich City on loan for the rest of the 2022–23 season. He made his debut on 25 February, scoring once and also providing an assist for Gabriel Sara in Norwich's 2–0 win against Cardiff City. Marquinhos received the first red card of his senior career on 15 March in Norwich's draw at Huddersfield Town after he appeared to elbow Josh Ruffels. However, Norwich successfully appealed the decision, and the…

As of match played on 1 June 2025

In May 2015, Marquinhos told Le Parisien that he had become engaged to Brazilian singer and reality television contestant Carol Cabrino. He proposed to her underneath the Eiffel Tower. They had a civil wedding in June 2016. Their daughter was born on 1 November 2017, with Cabrino having gone early into labour while watching Marquinhos playing a Champions League match against Anderlecht at the Parc des Princes. Their second child was born in December 2019, and their third in April 2022. During a match between PSG and Nantes on 14 March 2021, Marquinhos' parents were held hostage in a robbery. This came alongside teammate Ángel Di María's family being held hostage in a robbery at the same time.
