Having won their first leg 1-0 away last week, Olympiacos must avoid a defeat if they are to qualify to the next round of the competition. Goals from Sebastião Seba in the 27th minute separated both teams; however, it would take an element of luck for Arouca to overturn the result considering the fact that the host has made their stadium a slaughter slab for opponents.
Ideye would be targeting another starting shirt and victory on Thursday in a bid to keep his hope of winning a European laurel at the end of the season.
Meanwhile, Victor Moses is poise to make his presence count as Gent take a trip to confront NK Lokomotiva at the Stadion Kranjčevićeva.
Moses, who has been a regular starter in the team, will be hoping to deliver the goods for Gent in terms of scoring goal. The first leg ended 2-2 last week and a win for Gent will automatically qualify the team to the group stages of the competition.
