The Gunners take on the Championship outfit on Saturday at Wembley in the semi-final clash as they look to defend the coveted English trophy.
Arsenal came from behind to beat Hull in last year's final after edging Wigan in a tough battle the game before.
And Flamini reckons that last year's experiences show that Arsene Wenger's men can't afford to underestimate Reading, telling the club's official website: "Wigan definitely [gave us a warning] which is why we know exactly what to expect. The FA Cup is a very tough challenge and you have to give everything to win it.
We know it's never easy to win a trophy and we are very focused

"We know it's never easy to win a trophy and we are very focused. It won't be easy because we will play a very good team, but let's start with the semi-final, let's do the job properly and hopefully we will win it again this year.
"The first time [I won the FA Cup in 2005] was a great moment. I was at the club for three years and to win the FA Cup is always very important. It was a great moment, a great communion with the fans and I will always remember it.
"The second time was a chance [for me] to win a trophy straight away and there was a lot of emotion and happiness. The club didn't have the chance to win it for many years, so I was very happy it happened the year I came back."
