Early career Born in
Facobly,
ES Sétif Serey Dié was invited for a trial with
ES Sétif, and therefore moved to Algeria. This adventure nearly started and ended as a farce on the same day. As the club's president saw Serey Dié, he thought that the wrong player had been hired and sent him home. The coach asked Serey Dié to stay for the training, which he did and in a test match, he was able to convince the club's management to let him stay for a six-month trial. During this trial period, Serey Dié played well and ES Sétif won the
2007–08 Arab Champions League, but he refused to sign the contract that he was subsequently offered.
Sion Between 2008 and 2012, Serey Dié played for
Sion, with whom he won the
Swiss Cup twice. During March 2010, he came under suspicion of corruption in connection with betting manipulation. In May 2012, he was the subject of controversy after cameras filmed him slapping a thirteen-year-old ball-boy in the face. This was during the away game against
FC Lausanne-Sport on 2 May. This assault resulted in an eight match suspension.
Basel On 13 December 2012,
Basel announced the signing of Serey Dié on a three-and-a-half-year contract. He joined Basel's first team during the winter break of their
2013–14 season under head coach
Murat Yakin. He made his debut for Basel on 10 February 2013, in a 3–0 home win in
St. Jakob-Park against his former club, Sion. He scored his first goal for Basel, the first goal of the match, in a 4–0 away win against
Luzern in the
Swissporarena, on 1 April 2013. At the end of the
Swiss Super League season 2012–13 Serey Dié won the Championship title with the team. In the
2012–13 Swiss Cup Basel reached the final, but were runners up behind
Grasshopper Club, being defeated 4–3 on penalties, following a 1–1 draw after extra time. In the
2012–13 UEFA Europa League, Basel advanced as far as the
semi-finals, there being matched against the reigning
UEFA Champions League holders
Chelsea. Chelseas won both games and 5–2 on aggregate. At the end of the
2013–14 Super League season Serey Dié won the league championship with Basel. The team also reached the final of the
2013–14 Swiss Cup, but were beaten 2–0 by
Zürich after extra time. Basel joined the
2013–14 Champions League in the qualifying rounds and they advanced to the group stage. Finishing in third place in their group, Basel qualified for
Europa League knockout phase and here they advanced as far as the quarter-finals. But eventually they were beaten by
Valencia 5-3 on aggregate, after extra time. In their
2013–14 season, Basel played a total of 68 matches (36 Swiss League fixtures, 6 Swiss Cup, 6 Champions League and 10 Europa League and 10 test matches). Serey Dié totaled 38 appearances, 22 League, 3 Cup, 4 Champions League and 5 Europa League as well 4 in the test games. He scored 2 goals in these matches. The season 2014–15 was a successful one for Basel. However, Serey Dié's season was an unlucky and unthankful one under the new trainer
Paulo Sousa. Despite the fact that Basel won the championship for the sixth time in a row
that season and despite that Basel had entered the
Champions League in the
group stage, reaching the
knockout phase on 9 December 2014, as they managed a 1-1 draw at
Anfield against
Liverpool, Serey Dié totaled just 13 appearances during the first half of the season (7 League, 2 Cup, and just 2 in the Champions League, as well 2 further appearances in test games). Because Sousa did not rely on Serey Dié as a regular player, he was forced to leave the club and they club announced that he moved to
Stuttgart on 2 February 2015.
VfB Stuttgart On 2 February 2015, Serey Dié moved to
Stuttgart. After returning victorious from the
2015 Africa Cup of Nations, he featured in all but one of Stuttgart's remaining games, becoming a key member of the midfield. On 15 July 2016, Stuttgart announced that Serey Dié would return to
Basel.
Return to Basel Basel confirmed the transfer on the same day, stating that Serey Dié had signed a two-year contract. He joined Basel's first team for their
2016–17 season under head coach
Urs Fischer. At the end of the season, Serey Dié won the Swiss championship for the fourth time in his career. For the club, this was the eighth title in a row and their 20th championship title in total. They also won the
2016–17 Swiss Cup, defeating
Sion 3–0 in the final, which meant they had won the double. In
Basel's 2017–18 season Raphaël Wicky was appointed as new head coach. In the domestic league Basel ended the season in second position and in the Cup they reached the semi-final only to be defeated by
Young Boys. The team entered the
Champions League in the group stage, ending this in second position in the table. In the second half of the season Serey Dié was loaned out to
Xamax. Basel stated that the Africa-Cup was the reason for Serey Dié's move. The player himself stated "I couldn’t risk not playing as much with FCB in the 2nd half of the season. With regular appearances for Xamax I will be able to help my new club achieve their goals, as well preparing myself for the Africa-Cup with the Ivory Coast this summer." Following his loan period and his appearances at the
2019 Africa Cup of Nations, Basel and Serey Dié decided to dissolve their contract. Between the years 2012 to 2015 and again 2016 to 2019 Serey Dié played a total of 168 games for Basel scoring a total of six goals. 95 of these games were in the
Swiss Super League, 15 in the
Swiss Cup, 31 in the UEFA competitions (Champions League and Europa League) and 27 were friendly games. He scored all six goals in the domestic league.
Aarau and Xamax Serey Dié had a short spell with
Aarau and another short spell with
Xamax.
Return to Sion On 26 May 2020 it was confirmed, that Serey Dié had returned to the side where he started his European career seven years earlier,
FC Sion. Serey Dié signed a two-year deal. During the
2021–22 Super League season Serey Dié quietly and secretly resigned from his active football career, as can be seen from the transfer overview of the Swiss Football League. ==International career==
