"We have to be very proud of what we have done," Fabregas reflected.
"We went over to our fans, and you could also see some of the Milan fans clapping. You could see they like this kind of football and that we played well. They had a lot of respect for us.
"The Milan players too, they all said: 'well done, we hope you win it now'.
"Afterwards, when you look back on your career, these are the nights you are going to remember."
And Fabregas firmly believes the Gunners have the game to go all the way this season.
"Other teams know if they let us play, we can be very dangerous," he observed.
"They close us down and defend, we have to try not to make mistakes and just play our own football."
Fabregas declared: "The spirit of the team is amazing, and we have to keep going.
"Now, though, we just have to be focused on Sunday's game - we have to go to Wigan and win there."
