The Gunners must beat Olympiacos by two clear goals - or by any margin if they score three or more - when they travel to Athens on Wednesday night.
Arsene Wenger’s job will not be on the line when Arsenal faces Olympiacos in a do-or-die fixture for the club's Champions League hopes on Wednesday.
But the pressure from the supporters will once again start to weigh on Wenger if the Gunners fail to qualify for the knockout stages of the competition for a 16th season in a row.
Arsenal was supposed to stroll through this group with Bayern Munich, yet the club faces an unenviable task in Athens, where it arrives having lost three of five Champions League matches so far.
