In tandem with Cesc Fabregas, the Frenchman dominated the centre of the park as Arsène Wenger's side not only reached the Quarter-Finals but became the first English side to beat the Rossoneri at the San Siro.
Now Flamini feels the footballing world is their oyster.
"I'm going to say there's no limit [to how far we can go]," said the midfielder, 24 on Friday. "There are no limits because we are playing the Champions League to win it. We are playing the Premier League to win it too. So we are going to concentrate now. As you saw in the last two games to concentrate is very important at a very high level.
"Before this game everybody said that Arsenal was a young side with less experience. It's true we have less experience than Milan but we proved to everyone we have more experience [than people think].
"Two years ago we went to the Champions League Final. A lot of our players were in that team and we have added quality to that. We are stronger, we have more experience so I'm sure we will do a good job in the Champions League from now on."
There was a sense that Arsenal's entire season was in the balance on Tuesday night. They had seen their lead in the Premier League cut to one point and were facing a side that had reached the Final in three of the last five years.
"Of course to come here and beat the Champions League holders [is a boost]," said Flamini. "It was a great team performance. The spirit was fantastic especially in difficult moments. It made a difference. Everyone did a great job. We were all working for each other.
"I think we could have won the game in the first half because we had a lot of opportunities to score a goal and were a bit unlucky. But we pushed and pushed and pushed and finally we scored in the last 10 minutes. I think we deserved our victory.
"We were not especially nervous going into the game. It's true it was a little bit frustrating because on a big occasion like that if you cannot score then, at the end, you are under a little bit of pressure.
"But we knew we had the quality to score. In the first leg we had a lot of opportunities but didn't score. Tonight we did it, we pushed until the last minute and even scored a second one so overall it is a great victory, especially to come here in the San Siro. We are the first English team to win here at AC Milan. Now we are just going to enjoy this victory."Copyright 2016 The Arsenal Football Club plc.
