Diomède was born in Saint-Doulchard, Cher,^[5] to parents of Guadeloupean descent.^[6]

Diomède's career began with AJ Auxerre. After playing at youth level for the club, he made his Division 1 debut in 1992. He played in the first team during eight years, under Guy Roux Auxerre won the Division 1 and Coupe de France double in 1996. The winger scored 30 goals in 175 Ligue 1 matches for Auxerre.^[7]

In June 2000, Diomède was signed for £3m by then Liverpool F.C. manager Gérard Houllier.^[8] Making his debut against Sunderland, Diomède appeared to have scored with an overhead kick, but the goal was not given even though replays showed that the ball had crossed the line.^[9] However, he did not settle in England, and only played five matches for Liverpool. In January 2003, he was loaned out to AC Ajaccio, newly promoted in France's Ligue 1, until the end of his contract.^[10] After his spell at Liverpool had come to an end, he joined the Ligue 2 team Créteil, and then Clermont Foot in the Championnat National (3rd division).^{[citation needed]}
