Arsène Wenger admits winning away at Borussia Dortmund in Tuesday’s Champions League opener would give his side a massive boost.

Saturday’s victory against Swansea provided a timely lift to the Arsenal squad ahead of the trip to Germany for, what appears on paper, their toughest Group Stage fixture.

And, with Marseille and Olympiacos completing a difficult-looking Group F, Wenger knows the confidence an early win on the road could breed.

“It would create a certainty that we have a good chance to go through,” he said. “For us to get a positive result tomorrow night would be a big lift.

“It’s a good opportunity for us to get positive vibes and we need a bit of that. Every team, no matter how good they are, needs confidence and I believe my team needs that at the moment.”

Despite an impressive win in Belgrade on Matchday Two, Arsenal struggled away from home in Europe last season - losing three of their four games - but Wenger isn’t concerned by past results.

“For a long time we were quite successful away from home in the Champions League, it was just last season,” he said.

“Last year we had an early nine points and we dropped points after that, especially the game in Braga when we were really unlucky.

“If you get the records of all the managers playing away in the Champions League they are roughly the same.”
