Known for his pace and technical skills, Maatouk is the Lebanon national team's all-time top goalscorer and most-capped player, captaining the side from 2016 to 2024.

Maatouk began his senior career at age 17 in 2004 with Ahed in Lebanon, winning 12 trophies, including three league titles and three FA Cups in seven years.

In 2019, Maatouk joined cross-city rivals Ansar on a free transfer, leading them to their first league title in 14 years in 2021 as top scorer.

[6] However, his family's attempt to secure permanent residency in Germany was interrupted by a police raid,[6] forcing them to return to Lebanon in 1998 and ending Maatouk's opportunity of playing with Schalke.

Although the issue of lifetime contracts initially hindered his signing with Ahed, circumstances changed when Maatouk's father's minibus, the family's sole source of income, broke down.

[8] He made his debut on 28 September 2004, coming on as a substitute for Ali Attar against Olympic Beirut in the 2004 Lebanese Elite Cup group stage.

[20][34] He later said in an interview that during a match played for the Lebanon national team, against the United Arab Emirates on 6 September 2011, Ajman's coach was present and showed interest in signing him.

[47][48] On 22 October 2014, Maatouk assisted Boubacar Sanogo's opening goal in a 2–1 victory over Ittihad Kalba, Fujairah's first win of the 2014–15 season.

[15] He was released by Fujairah in July 2017;[56] the Lebanese player's desire to terminate his contract came after his team failed to gain promotion to the first division during the 2016–17 season.

[67] This enabled Nejmeh to gain all three points and qualify to the Round of 36 against Al Ahly, where his team lost 4–1 on aggregate and was subsequently knocked out of the competition.

[69] On 25 August 2018, Maatouk won his second consecutive Elite Cup for Nejmeh, his fifth in total,[70][24] after beating Akhaa Ahli Aley 1–0 in the final.

[74] On 6 April 2019, Maatouk's penalty kick allowed his team to beat Ansar 1–0 in the Beirut derby, in a vital fight for second place.

[78] On 3 July 2019, cross-city rivals Ansar announced the signing of Maatouk on a three-year deal after his previous contract with Nejmeh had expired.

[79] Maatouk scored his first goal for Ansar on 24 July 2019, in the 2019 Lebanese Elite Cup group stage game against his former club Nejmeh.

[83] Maatouk made his league debut for Ansar on 20 September 2019, in the Beirut derby against Nejmeh, which his side lost 1–0 due to a 90th-minute penalty by Feiz Shamsin.

[85] In January 2020, the Lebanese Football Association decided to suspend the ongoing 2019–20 season due to financial and political issues in the country, as well as the COVID-19 pandemic.

[86] On 24 February 2020, Maatouk scored a header against Al-Faisaly in a 2020 AFC Cup group stage game, helping Ansar to a 4–3 home victory.

[88] In the following game on 18 October, he scored a brace against Chabab Ghazieh, including a direct corner kick goal aided by strong wind, helping Ansar reach the top of the table.

[1] On 6 August 2023, Maatouk began the 2023–24 season with a free-kick goal and an assist in the first matchday of the league, resulting in a 2–2 draw against Ahly Nabatieh.

[106] Despite eventually finishing runners-up in the league to Nejmeh,[107] Ansar won the FA Cup after defeating Ahed 2–1 in the final on 11 July 2024.

[112] Maatouk's first goal came in 2011 at the 2014 FIFA World Cup qualifiers, during the first leg of the second round game against Bangladesh; he scored the opener in a match that finished 4–0.

[121][122] In the 53rd minute, Maatouk scored a low-driven shot on a volley from a free kick taken by Abbas Ahmed Atwi to put his team in the lead.

[124] After the second round of the World Cup qualifiers in 2016, national team captain Roda Antar retired from international football, with Maatouk taking over the reigns.

[127] In the first group stage match, on 9 January 2019 against Qatar, he received a yellow card for an alleged "handball", protecting his face with his arm;[128] the opposing team scored from the subsequent free kick.

[130] On 19 November 2022, in a friendly against Kuwait in Dubai, United Arab Emirates, Maatouk played his 100th game for Lebanon,[131] becoming the first player from his country to join the FIFA Century Club.

[1] He played his last game for Lebanon on 11 June 2024, in the final match of the second round of 2026 World Cup qualification, scoring a hat-trick in a 4–0 win against Bangladesh.

[146] In 2012, Lebanon national team's coach Theo Bücker described Maatouk as a player who "comes around every 10 years" and "is almost impossible to substitute."

His manager at Ajman, Abdulwahab Abdulkadir, praised Maatouk's speed, ability to beat many players, and hard work.

[7] In a 2024 interview, he credited coach Jamal Al Haj at Ahed, who, according to Maatouk, "not only believed in my talent but also knew how to guide it on the right path".

[151] Maatouk, representing Lebanon, starred in the first season alongside Thiago Silva (Brazil), Luka Modrić (Croatia), Pierre-Emerick Aubameyang (Gabon), Andre Blake (Jamaica), and Brian Kaltak (Vanuatu).
