Egypt striker Ahmed 'Kouka' Hassan netted his first goal for Olympiacos after re-joining them on loan from Portugal's Braga, leading them to a 1-0 Greek league win over Atromitos on Sunday.
The 26-year-old started on the bench before being introduced in the 59th minute to mark his third appearance with Olympiacos with a precious stoppage-time winner.
Kouka moved to Olympiacos on a short-term loan deal last month. He also spent last season with the Greek giants, where he scored 15 goals in 32 appearances.
He scored only one goal in seven appearances with Braga this term.
Kouka, who came from Ahly's youth ranks and began his European career with Portugal's Rio Ave in 2011, has 25 international caps, scoring five goals.
Olympiacos moved top of the table with 57 points, two ahead of second-placed PAOK.
