The defender believes they can secure victory in Germany after the famous 2-0 win last time around.
The Gunners travel to the Allianz Arena this week looking to beat the German giants once again, having managed to beat them 2-0 at the Emirates Stadium last time around.
That was a big result for the side and kept their Champions League hopes alive, and came after they changed their tactics to be more defensive and catch Pep Guardiola’s on the counter attack.
And Gabriel says they must do a similar thing in the away game, and attack with intelligence, to secure another famous victory.
“I think at home we were able to impose ourselves but I think when we play away, we also have to have a slightly different outlook,” he told arsenal.com.
“That doesn’t mean we’ll spend the whole game defending but we need to attack with intelligence and make sure we don’t suffer a defeat and complicate our situation for the rest of our competition.”
After losing their first two games in Europe, many are expecting them to head out of the competition, but Gabriel insists that they are confident within the competition.
The Gunners have been in fine form in recent weeks, including the win over Bayern, and now find themselves joint top of the Premier League table, with only goal difference putting Manchester City ahead of them.
And the defender says that the win in London has given the side belief that anything is possible for them this season.
“I think we feel more confident within the competition than after the first two games,” he added.
“With this victory, we managed to get up and running and realise that anything is possible in football, thanks to the confidence and ability of all the players.”
