Cesc Fabregas is convinced Arsenal's victory at AC Milan has given them the surge of self-belief needed as they chase a Premiership and Champions League Double.
"We have to be very proud of what we have done," Fabregas reflected.
"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."
Next up for the Gunners are Wigan on Sunday, when Wenger's men can extend their lead at the top of the Barclays Premier League over Manchester United, who are in FA Cup action against Portsmouth.
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."
