Arsene Wenger believes Sunday's thrilling win over Aston Villa proved Arsenal have the mental capabilities to win the FA Cup this season.
The Gunners found themselves 2-0 down at half-time, after goals from Richard Dunne and then Darren Bent left the Emirates Stadium crowd in complete shock.
Having been booed going into the break by their own fans, Arsenal responded in the second period with three goals in a dramatic seven minutes to win the fourth round tie.
Firstly, Aaron Ramsey was felled by Dunne in the penalty area and Robin van Persie dispatched his 28th goal of the season from the spot.
The Gunners were then level three minutes later after a clearance from Alan Hutton cannoned into the net off the midriff of Theo Walcott, before the home side were awarded another spot-kick.
This time Bent brought down Laurent Koscienly and van Persie converted the resulting penalty to seal Arsenal's progress into the fifth round.
And Wenger was delighted with the spirit his players displayed in the second 45 minutes, and believes Arsenal have what it takes to go all the way in the competition.
"It was a good test to show that we had the mental qualities to come back," he told Arsenal.com.
"On the other hand it was important that we didn't panic [at half time].
"To concede a goal just on half time for 2-0 was a difficult blow, but we responded very well against Manchester United here [last week] and we did it again today.
"Overall it was a classic FA Cup tie, 2-0 down and we came back. We had to fight to score three goals and we did it well."
He added: "Last year was a learning process. We went for four trophies and in February we were still in all four.
"When we had to play the Carling Cup final we were a bit nervous because we hadn't delivered, but they have learnt from that.
"Hopefully we can show it this year."
