Arsenal do not offer as much of an attacking threat as they have in previous seasons, and as a result, Olympiacos can go into tonight's game with every confidence of getting three points insists goalkeeper Franco Costanzo.
The 31-year-old Argentine international knows the Greek outfit will face a stern test at the Emirates Stadium this evening, but says that will spur the players on to get a result.
"Arsenal is always is a dangerous team but this season they do not offer so much fear in attack as they did in [the] past," Costanzo told skysports.com.
"They have lost Cesc Fabregas and Samir Nasri and they are significant and will mean they get less chances in any match.
"But I still do not expect the habitual direct game from an English club, there is still a difference between the Gunners and other clubs."
After losing their opening UEFA Champions League Group F game against Marseille, the South American stopper knows Olympiacos cannot afford another poor result against Arsene Wenger's young Gunners, and says the belief amongst the players is strong.
"Arsenal in London always offer a lot of danger," Costanzo continued. "But we travel looking to win - one point would not be bad, but we want three.
"Arsenal are more vulnerable this season and Olympiacos could win if we play with intelligence."
