Wojciech Szczesny believes momentum has been a key component of Arsenal's recent winning run.
Victory in Marseille on Wednesday night was the team's sixth in succession and Arsene Wenger's side have also won their last 10 matches on the road in all competitions.
Szczesny says a "desire" to defend well has aided that form and is confident that the team can continue to prosper.
"When you defend very well for 90 minutes, you are going to get a couple of chances to score on the counter-attack"
"We've won the last six games, four of them away from home," he told Arsenal Player. "We know the momentum is with us. The games are coming thick and fast because we play in every midweek game so I'm sure we can keep that going, keep the momentum going and keep getting results.
"I think it's just the desire of the whole team to defend well. We've not conceded a lot of goals away from home. We've been defending really well and then scoring goals on the counter attack so it's just consistency of our defensive performances I think.
"When you defend very well for 90 minutes, you are going to get a couple of chances to score on the counter-attack and that's what we've been doing away from home.
"It doesn't really matter for us who scores first as long as we're the ones who score more goals at the end of the game. We hope we can keep it going."
Jordan Ayew's injury-time penalty ensured a nervy finale at Stade Velodrome and Szczesny was disappointed to miss out on a clean sheet for the second successive game.
"The penalties are not making me happy at the moment," he said. "There have been too many of them and they take my clean sheets away but three points are the most important and we got them [on Wednesday]."
