He spent the majority of his career in Greece and is best known for his tenure at Greek side Ergotelis, for which he still remains the all-time top scorer.
As he was deemed too young to be included among his manager's Eugene Gerards' plans, he returned to Greece in 2002 and signed for Cretan club Ergotelis, which played in the Greek Gamma Ethniki at the time.
He followed up with another 9 goals in his second season, helping the club gain another promotion, this time in the Alpha Ethniki, Greece's top tier football division.
Then Ogunsoto became instrumental in the club's second promotion and winning of the division title, by being declared top-scorer once again with a total of 21 goals at the end of the 2005−06 season.
Despite reported interest from Dutch Eredivisie and Russian Premier League clubs, Ogunsoto remained for a second season with Westerlo, making 10 appearances and scoring no goals.
However, tensions rose between the player and manager Nikos Karageorgiou, which led to an eventual fallout with the club's board of directors.
On the winter transfer window of 2009, Ogunsoto was loaned to local rival OFI, playing in the Beta Ethniki on a six-month deal.
In winter transfer window he moved to Olympiakos Volou, and ironically scored his first goal against his former team Ergotelis in a 2-0 home win.
[6] Three months later however, he would terminate his contract with the club after realizing he was not counted among the first choices of Ermionida manager Roberto Bolano.
Lashing out against the referee for poor officiating, Ogunsoto delivered his infamous «Pos genen afto» speech (roughly translated as «How can this happen»), which has since spawned many memes and is frequently used as a catchphrase across Greece and Greek media.
