Pintér won the Hungarian League title with Ferencváros in the 2003–04 season. Pintér also could win the Hungarian Cup in 2004. He was dismissed from the club in 2004 after what was claimed to be a contract negotiation problem. Shortly after, the players of the club released a statement about Pintér's apparent behaviour during his tenure: according to the team, profanity, hazing, racist slurs and bullying was commonplace.
Attila Pintér became the coach of the Győri ETO FC in 2009. During his coaching the team finished third in the Hungarian League 2009–10 season after beating Videoton FC in the last round. On international turf the team entered the Europa League 2010-11 season. In the first qualifying round Győr played their first match against FC Nitra. The final result was 2–2. In the second leg Attila Pintér's team could win 3–1 at the ETO Park. In the second qualifying round Győr played their first match in Kazakhstan against Atyrau. The match finished 2–0 to Győr thanks to the goals of Linas Pilibaitis and Fouad Bouguerra. In the second leg Győr could win 2–0. The goals were scored by Rati Aleksidze and Mihai Nicorec. In the third qualifying round Győr played with the FrenchMontpellier HSC. The first match was played at the ETO Park and the final result was 1–0 to the French team. The only goal of the match was scored by Olivier Giroud. In the second leg Győr won 1–0. The only goal was scored by Valentin Babić. In extra time there were no more goals therefore the teams had to decide the match in the penalty shootout. Győr won 4–3 on penalties and entered the play-offs of the Europa League. Győr played the CroatianDinamo Zagreb in the play-off of the Europa League 2010-11. The first match was won by Zagreb 2–0. In the second leg at the Stadion Maksimir győr lost to 2–1 and were eliminated from the Europa League on 4–1 aggregate. Due to the increase of the number of matches the team were unable to do well both in the Hungarian League and in the Europa League. The results in the domestic league were not satisfying for the management, therefore Attila Pintér and the management mutually terminated the contract between each other and the management appointed Aurél Csertői as the manager. On 12 May 2013, Attila Pintér's Győr ended a 30-year wait for the Hungarian League title by beating Ferencvárosi TC at home by 1–0, while their rival Videoton FC lost to Debreceni VSC 2–1 in the 27th weekday of the championship. In the 2012–13 season they went on a 22-match unbeaten run before back-to-back defeats knocked them off their stride. But neither Videoton FC nor MTK Budapest FC could sustain the challenge therefore Győr could wrap up their fourth title with room to spare. On 22 May 2013, Pintér could have led Győr to double their success by winning the 2012–13 Magyar Kupa against Debreceni VSC at the Bozsik Stadion, Budapest. Győr was winning by 1–0 thanks to the goal by Nemanja Andrić in the 19th minute but in the second half Debrecen's Adamo Coulibaly scored two goals which resulted Debrecen's victory over Győr in the Hungarian Cup final.
