Early career Born in
Nuoro,
Sardinia, Italy, Sirigu started his football career in
Venezia's youth system playing as a
midfielder. He was known for his powerful back heels, which he used to take penalty kicks. He had been training as an attacker for a local amateur side, Puri e Forti, at 11 years old when coaches concluded that his
asthma condition would hinder him too much as an outfield player. Instead, observing Sirigu's extensive hands, they told him to have a go at the goal.
Palermo In 2002, he joined
Palermo's youth system. In the 2006–07 season, he made his debut as a starter in a
Coppa Italia match against
Sampdoria and a
UEFA Cup match against
Fenerbahçe. Palermo loaned him to
Serie C1 club
Cremonese on 12 July 2007 to gain some first team experience. He spent the 2008–09 season on loan to
Serie B side
Ancona, but only played 15 games with his club, as Ancona managers
Francesco Monaco, and later
Sandro Salvioni preferred Brazilian
Da Costa over him. Sirigu successively returned to Palermo as a second-choice keeper, behind new signing
Rubinho, for the
2009–10 season. Following a string of unimpressive performances by Rubinho, Palermo coach
Walter Zenga, himself a former goalkeeper who was noted for his ability, elevated Sirigu to the starting role for the Week 6 game, an away match against
Davide Ballardini's
Lazio on 27 September 2009. The game, which also represented Sirigu's official debut in the Italian Serie A, ended in a 1–1 draw, with the young goalkeeper being nominated Man of the Match due to his numerous saves throughout the match. He was subsequently confirmed for the following game, where Sirigu managed to keep a clean sheet in a 2–0 win against Serie A giants
Juventus. Since then, Sirigu was regularly featured in the starting line-up and permanently confirmed as the first-choice goalkeeper, leading the club to send Rubinho out on loan to
Livorno later in January. Due to his performance during his time at Palermo, Sirigu earned the nickname "Walterino," a reference to his coach, Walter Zenga, who is regarded as one of the greatest goalkeepers of all time. On 21 October 2009, Palermo announced to have agreed a contract extension with him, the new contract would have expired in June 2014. His final appearance for Palermo came in the
2011 Coppa Italia Final against
Internazionale at Rome's
Stadio Olimpico, a 3–1 loss.
Paris Saint-Germain in January 2015 On 28 July 2011, Sirigu signed a four-year contract with French club
Paris Saint-Germain for a transfer fee of €3.895 million. Although initially signed as a reserve for
Nicolas Douchez, Sirigu started all 38
Ligue 1 matches during his first season at the club as PSG finished as runners-up to
Montpellier HSC. On 27 January 2013, Sirigu broke
Bernard Lama's clean-sheet record for a PSG goalkeeper in Ligue 1 (697 minutes). He became the first foreign player to be named
UNFP's goalkeeper of the season as PSG won the
2012–13 Ligue 1 championship. Sirigu won the award for the second consecutive year in 2014, with PSG defending their league title and winning the
Coupe de la Ligue. On 2 August 2014, as PSG won the
Trophée des Champions 2–0 against
Guingamp at the
Workers Stadium in
Beijing, Sirigu saved a 32nd-minute penalty kick from
Mustapha Yatabaré. He signed a contract extension on 10 September of the same year, lasting until 2018. Sirigu remained PSG's first choice goalkeeper in the 2014–15 season for
Ligue 1 and
UEFA Champions League matches, as the capital club won a
domestic treble of the league championship,
Coupe de France and
Coupe de la Ligue, as well as reaching the quarter-finals of the Champions League. After PSG completed the signing of German goalkeeper
Kevin Trapp from
Eintracht Frankfurt in July 2015, deputy sporting director Olivier Letang announced that the club "would not stand in [Sirigu's] way" if he wished to leave Paris. However, the player's agent denied that the player would leave the club. Sirigu remained PSG's first choice goalkeeper in the
Coupe de France and
Coupe de la Ligue, winning both titles, with Trapp taking his place as the preferred choice in
Ligue 1 and
UEFA Champions League matches. On 12 February 2016, he announced that he would have left PSG during the previous winter
transfer window if "an important proposal had arrived", but ultimately remained with the club for the remainder of the season.
Loans to Sevilla and Osasuna On 26 August 2016, Sirigu joined
La Liga club
Sevilla FC on a season-long loan. He made his debut with the club in a 1–1 away draw against
Eibar on 17 September. A week later, away to
Athletic Bilbao, he was sent off for elbowing
Aritz Aduriz, leaving midfielder
Vicente Iborra to unsuccessfully face the former's penalty in a 3–1 loss. Having made only three appearances for the
Andalusians, Sirigu moved to fellow league club, strugglers
CA Osasuna on 31 January 2017 for the remainder of the season.
Torino On 27 June 2017,
Torino announced they had signed Sirigu on a
free transfer. He made his debut for Torino on 12 August, in a 7–1 home win against
Trapani in the
Coppa Italia third round, and eight days later made a first Serie A appearance in a 1–1 draw away to
Bologna. In July 2018, when Sirigu had a year left on his contract, he extended it until June 2022. On 3 March 2019, he recorded his sixth consecutive Serie A clean sheet, thereby surpassing
Luciano Castellini's club record of 517 minutes without conceding a goal in Serie A. On 15 July 2021, his contract with Torino was terminated by mutual consent.
Later career On 3 August 2021, Sirigu joined
Genoa, stating that his aim was to be chosen by Italy for the
2022 FIFA World Cup. Having missed only the last game of his one season at the
Stadio Luigi Ferraris, he then joined
Napoli on a free transfer. Having not played at all for Napoli, Sirigu transferred to
Fiorentina on 25 January 2023. After playing two games – one in the
UEFA Europa Conference League – he suffered an
Achilles tendon injury in March, ruling him out for an estimated six months; his contract was set to expire in June, but included a one-year extension option. On 15 September 2023, Sirigu joined
Ligue 1 side
OGC Nice on a one-year deal. On 16 January 2024, after failing to make an appearance during 124 days at Nice, Sirigu left the club and joined Turkish
Süper Lig club
Fatih Karagümrük. He left the club by the end of the season following the expiration of his contract. On 24 August 2024, Sirigu signed a one-year deal with Serie B club
Palermo, thus returning to the
Rosanero thirteen years after his departure. ==International career==
