Arsenal fans marvel at defence on Twitter: Per the pickpocketer!

The Gunners defence marked Dortmund's attack so tight that Reus, Lewandowski and co would have gone home feeling lonely.

Arsenal parked the proverbial bus in front of goal for a large portion of their Champions League match against Borussia Dortmund, breaking down the infamous Westfalenstadion Yellow Wall and stealing a victory courtesy of an Aaron Ramsey header on the hour mark on Wednesday, November 6.

However, it was not Ramsey's heroics that dominated timelines on Twitter. Neither was it the assist that came via patient target-man Olivier Giroud. No… the players most praised for their performance at Signal Iduna Park were the two previously identified as the Gunners' danger men by BVB manager Jurgen Klopp: Per Mertesacker and Laurent Koscielny.

Ahead of the game, Klopp claimed Lewandowski would have to be patient as the famed forward would have to 'impose his game'. Instead, the reverse was true as the Mertielny/Kosacker axis at the back stamped out a plethora of through balls, were at their intercepting and blocking best and made key challenges where necessary.

Ramsey's goal was struck against the run of play and, incidentally, was Arsenal's first shot on goal, however, it swung the momentum in their favour as they piled on the pressure.

Arsene Wenger's Gunners now top Group F of the Champions League with a haul of nine points from a possible 12 to date. They edge second-placed Napoli by a goal differential of plus two, while Dortmund are now third, with six points.
