Serey Die started his football for Centre National des Sports de Haut Niveau in Abidjan. He played one year for Volcan Junior and one year for CO Korhogo before moving to top team Stade d'Abidjan in 2003. Three years later he moved to EO Goulette et Kram in Tunisia. But this was also to remain a short stay, he cancelled his contract himself after just half a year.
Then Serey Die 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 Die he thought that the wrong player had been hired and sent him home. The coach asked Serey Die to stay for the training, which he did and in a test match was able to convince the club's management to let him stay for a six-month trial. During this trial period Serey Die played well and ES Sétif won the 2007–08 Arab Champions League. But he refused to sign the contact that he was subsequently offered.
Between 2008 and 2012 Serey Die played for FC Sion, with whom he won the Swiss Cup twice. During March 2010, Serey Die 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.
On 13 December 2012, FC Basel announced that they had signed Serey Die on a three and a half year contract. Serey Die played his debut for Basel on 10 February 2013 in the 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 the 4–0 away win against Luzern in the Swissporarena on 1 April 2013. At the end of the Swiss Super League season 2012–13, he won the Championship title and was Swiss Cup runner up with Basel. 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, but were knocked out being beaten 2–5 on aggregate.
At the end of the 2013–14 Super League season Serey Die won his second league championship with Basel. They also reached the final of the 2013–14 Swiss Cup, but were beaten 2–0 by Zürich after extra time. In the 2013–14 Champions League season Basel in the group stage finished the group in third position to qualify for Europa League knockout phase and here they advanced as far as the quarter-finals. In their season 2013–14 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 Die 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.
In 2014, during Ivory Coast's match against Colombia, Serey Die was crying from the intensity and excitement he felt while representing his national team. Despite rumors of his emotional feelings was for his father's death, this was inaccurate. His father did not die that day, his father actually died in 2004
