Ideye chased down a nothing ball from Dimitris Siovas, before squeezing the ball home past Dinamo keeper Eduardo.
That goal from Ideye was his third consecutive goal in three games.
It was smash and grab for Olympiacos, who were mostly restricted to shots from distance but made their best opening count when Ideye scored for the third match in a row to snatch the points.
Just after the game, Brown Ideye took to his Instagram page to show gratitude to God and and his fans. His photo however triggered a reaction from former Super Eagles captain Vincent Enyeama in his Instagram handle (Vinny2908).
Ideye, fell out of manager Tony Pulis’ plans at West Brom after the recent arrivals of strikers Rickie Lambert from Liverpool and Salomon Rondon from Zenit.
The 26-year-old scored just four goals in 26 league appearances for the English club West Brom after joining in July 2014 from Dynamo Kyiv for a then club-record 10 million pounds ($15.4M), but failed to live up to his price tag at The Hawthorns.
