Montpellier in 2012 Stambouli spent eight months as a child at
Marseille, and also had two years at
Sedan before joining the ranks of
Montpellier in July 2004. Stambouli made his professional debut on 8 August 2010 on the first day of the
2010–11 Ligue 1 season, playing the full 90 minutes of a 1–0 home win over
Bordeaux. During the 2011–12 season, he played 26 league games as Montpellier won the Ligue 1 title for the first time in the club's history. During the 2013–14 season, Stambouli played 37 out of Montpellier's 38 league games and was promoted to position of vice-captain behind Brazilian
Vitorino Hilton.
Tottenham Hotspur On 1 September 2014, Stambouli signed for
Premier League team
Tottenham Hotspur for an undisclosed fee, rumoured to be in the region of £4.7 million. He scored his only goal for the club in a
UEFA Europa League match against
Partizan on 27 November, following up a shot from
Roberto Soldado, which had rebounded off of the post. Stambouli appeared in every round of the
League Cup as Tottenham reached the final at
Wembley where, however, Stambouli was an unused substitute as Tottenham were beaten 2–0 by Chelsea. At the conclusion of his first year at Spurs, Stambouli had made just 12 appearances in the Premier League.
Paris Saint-Germain On 20 July 2015,
Paris Saint-Germain manager
Laurent Blanc confirmed Stambouli would be joining PSG for a fee of £6 million, £1.3 million more than Tottenham had paid a year earlier. He made his debut on 1 August in the
2015 Trophée des Champions at the
Stade Saputo in Montreal, playing the final 20 minutes in place of
Marco Verratti in a 2–0 victory over
Lyon. Stambouli played 40 total matches for PSG, winning all four domestic trophies in his one whole season, but did not score and assist and was unpopular with some fans due to his connections to their rival Marseille. His final match was the
2016 Trophée des Champions, which his team won 4–1 against Lyon in Austria. He made his debut on 9 September in a 2–0 home loss to reigning champions
FC Bayern Munich. On 20 May, he was sent off for unsportsmanlike conduct in the last game of the season, a 1–1 draw at
FC Ingolstadt 04, and suspended for two matches. Stambouli suffered a
metatarsal injury in October 2019, ruling him out for the rest of the season. On 4 August 2020, he extended his contract with Schalke until 2023. Due to a clause in that deal, he left following their relegation in May 2021.
Adana Demirspor On 26 July 2021, Stambouli joined Turkish club
Adana Demirspor on a two-year contract. He was one of a number of high-profile players joining the newly promoted
Süper Lig club that summer, including
Mario Balotelli. He quickly became a key player in his first season, contributing 2 goals and 4 assists in 32 league matches. Stambouli maintained his consistency in second season, playing in 30 matches and scoring 1 goal and 5 assists. His successful performance led to his contract being extended for another two years. He was the captain of the team in the 2023–24 season. He scored the first goal of Adana Demirspor in the European cup qualifying history against
Cluj in the
UEFA European Conference League in that season. On 31 January 2024, the club announced that they have a mutual agreement with Stambouli to end his contract.
