Aaron Ramsey netted the only goal in a classic smash and grab triumph at Signal Iduna Park as the Gunners remained top of their group in Europe's premier club competition and the Welshman was ecstatic after a tough win away from home.
"It was a great achievement from the lads. It is always a difficult place to come. We realise that from the last time we came here and drew 1-1," he told Sky Sports.
"They got to the final last year and were unlucky and they are a strong team so we had to do our defensive work.
"We were very good defensively even though we didn't have any shots in the first half and they had a few, even if it was from distance.
"We kept our shape really well, we were patient and it was a proper away performance from the lads and we got them on the counter-attack."
