Ideye's late winner steals the points for Olympiacos
Olympiacos's chances of qualifying from UEFA Champions League Group F were boosted by a late win against Dinamo Zagreb.
Brown Ideye scored a late goal to give Olympiacos a priceless 1-0 away win at Dinamo Zagreb in UEFA Champions League Group F.
The striker chased down a nothing ball from Dimitris Siovas and squeezed the ball home past Eduardo from a tight angle with just 12 minutes left.
Dinamo had missed the game's best chances earlier in the second half with its captain Domagoj Antolic and Marko Rog both hitting the post.
But it could not break the deadlock and succumbed to its first defeat on home soil since a 5-1 reverse to Red Bull Salzburg in the Europa League last November.
It was smash and grab for Olympiacos, which was mostly restricted to shots from distance but made its best opening count when Ideye scored for the third match in a row to snatch the points.
The Greek side now looks well-placed to qualify from Group F with six points from its three fixtures and a home clash with the Croatians to follow.
Dinamo may argue it deserved more, having dominated the opening stages, with Rog particularly threatening. The winger did brilliantly down the left to beat his man but Siovas cleared for Olympiacos with nobody attacking the cross.
El Arbi Soudani then attacked down the opposite wing and cut inside to open up a sight of goal, only to waste the chance and shoot well wide, before the Algerian set up Junior Fernandes, who shot straight at Dinamo goalkeeper Roberto.
Dinamo then put together the finest move of the match but the flowing attack came to a stuttering end when Soudani picked out Armin Hodzic in the box, but the striker was well marshalled by the determined Olympiacos defence and failed to get a shot away.
Olympiacos was being restricted to shots from distance, with Arthur Masuaku forcing Dinamo keeper Eduardo into his first action of the game on the half hour with a swerving strike from distance, but the goalkeeper was alert to the danger.
Both sides opened up after the cagey first half and Dinamo skipper Antolic should have opened the scoring shortly after the break, but with the host suddenly four-on-two, his shot hit the outside of the post.
Olympiacos ought to have compounded that error immediately but Ideye could not convert a low cross from Pardo with Eduardo stranded.
Kostas Fortounis slashed wildly off target from distance as the Greeks committed more men forward in their attacks and Ideye atoned for his earlier miss by scoring a fine solo goal, beating Eduardo from near the byline after chasing down a long pass over the top.
Dinamo threw men forward but could not find a late response and their qualification chances now look slim.
