Jean Michaël Seri was born on 19 July, 1991. He is an Ivorian footballer who plays as a central midfielder for OGC Nice in the Ligue 1. In his native Ivory Coast, the young Michael was nicknamed Galla, because he tried to emulate the former Monaco and Paris Saint-Germain midfielder Marcelo Gallardo, whose technical skills he admired. He joined the Ivorian football academy that was opened in 2001 by the Ivorian footballer Cyrille Domoraud. “Jean is gifted, intelligent and respectful,” Domoraud said in retrospect. “In his young days, he was one step ahead of the others, thanks to his ball control.
On 2 November 2012, Seri joined Primeira Liga club FC Porto on loan, after impressing their scouts. But somehow there was no place for Seri in the club’s first team. He was thus forced to play for the club’s reserve team, scoring 1 goal in 19 Segunda Liga matches in the first five months of 2013. On 31 August 2013, two months after finishing his loan spell at Porto (the Dragões), Seri joined another Primeira Liga club Paços de Ferreira on a permanent basis and on a free transfer by signing a three-year deal. He debuted for the Pacenses on 14 September 2013 against Benfica in a Primeira Liga 3–1 away loss.
On 11 June 2015, Seri officially joined Ligue 1 club Nice for a transfer fee of €1 million. On 27 May 2015, prior to the opening of the transfer window, the club had announced the “very likely” arrival of Seri. On 8 August 2015, Seri made his competitive debut for Nice in their opening match of the 2015–16 Ligue 1 season, playing the entire match in the 2–1 home loss to Monaco.
