What a night for Arsenal. No one gave them too much hope of beating Pep Guardiola’s German champions who had won all 12 of their games this season. But with their backs against the walls for most of the second half, Arsenal managed to pull a rabbit out of the hat and seal a famous win.

The Germans had 70% of the possession, but it didn’t matter. Theo Walcott was only a Manuel Neuer iron wrist away from scoring in the first half and then he looked to have made another fabulous stop right at the death, but the ball had crossed the line. It was the story of the Germany keeper’s night – his wonderful save just wasn’t enough. And Arsenal live to fight another midweek evening in the Champions League.

It was a pulsating night in the Champions League, and Arsenal will be trying to make it 16 seasons in a row in the Champions League knockout round, but because of results in other games, they’ll have to hit great Champions League form over the next few months.

Here are three things we’ve learned from tonight’s action.

Manuel Neuer is a hero and a villain

Author of a fantastic save to break Arsenal hearts in the first half, and then author of a terrible piece of goalkeeping under the high ball to send Arsenal fans into raptures in the second half. He giveth and he taketh away.

English teams aren’t good enough off the ball

Bayern’s pressing showed just how good they are at doing it, but it also showed just how bad English teams are at it, too. Even though Arsenal won the game, Bayern had all the possession but they didn’t make it count. If English teams are to do better in Europe, they’ll need to get better at winning the ball back without going overboard.

But who cares, right? Arsenal won the game 2-0 without the ball. Arsene Wenger, take a bow. You won it like a boss!

Arsenal’s Champions League campaign is still alive

Just. A win tonight was a huge first step, but after such a disastrous start to the campaign it will still be tough. Especially given the win for Olympiacos tonight. That means that despite the win tonight, the Gunners are still in a precarious position.

If they lose next time away to Bayern and Olympiacos win at home to Zagreb, Arsenal will be six points behind second spot with only two games to go. And with head to head counting before goal difference, Arsenal would need to go out to Greece and score three goals.
