Arsenal boss Arsene Wenger says the Gunners must get all three points when they face Galatasaray on Wednesday night.
Having lost their first game away from home against Borussia Dortmund, Wenger's men know that they cannot afford another defeat if they are to continue their Champions League campaign.
"The group stage is a minimum of 10 points so the home games are vital," Wenger said on Tuesday.
"We had a disappointing result in Dortmund and at the moment I feel that the potential is there for us.
"We don't lose a lot but we want to find the winning edge together and we have that opportunity [on Wednesday].
"It's early but we are maybe more under pressure to win the game than if we had won the first.
"But it is the same in the Champions League - you want to win your home games. You need one good result away from home and then win all your home games."
