Will Francis Coquelin return for Arsenal against Olympiacos? “We will see,” says Gunners boss Arsene Wenger.
Mikel Arteta and Mathieu Flamini have both been ruled out of the must-win clash with the Greek side.
Flamini started Saturday’s 5-2 win over Leicester but was replaced by Arteta after suffering a hamstring injury. The Spaniard then picked up a dead leg.
Striker Olivier Giroud must serve a one-match ban following his red card against Dinamo Zagreb, but defender Gabriel is available following a domestic suspension.
When asked whether victory was imperative, Wenger replied: “You have to win your home games if you want to qualify from the group stage, it is simple as that. We cannot afford to drop points now against anyone at home.
“Olympiacos dominates their league, they are a team with a big advantage – they dominate their league easily, so they can prepare for these kinds of games.
“They are well organised and have some players who know the Premier League, like (Esteban) Cambiasso and (Pajtim) Kasami who both played in England.”
