Striker Danny Graham believes Swansea City can build on their recent momentum as they prepare for clashes against Sunderland and Chelsea.
"To win 3-2 against Arsenal just fills everyone with belief," said striker Graham, who scored the winning goal.
"Everyone is looking forward to next week's game now. It's a massive scalp."
Swansea showed great resolve to come back twice, firstly after an early Robin van Persie strike gave the Gunners a 1-0 lead, and when Graham scored the winner only seconds after Theo Walcott made it 2-2.
That was after a Scott Sinclair penalty had cancelled out van Persie's opener before Nathan Dyer had put the Swans 2-1 up.
All three of Swansea's English scorers impressed in front of England manager Fabio Capello.
"To go 1-0 down and come back shows true belief in the squad and everyone' buzzing to be honest," added Graham.
"It showed great character for us to go up the other end and score the third and see out the game.
"We are on a great run now and we want to keep the momentum going.
That momentum will be tested on Saturday at Sunderland, where new manager Martin O'Neill has overseen five wins and a draw in his opening eight games in charge.
But Sunderland went down 1-0 at the weekend to Chelsea, who arrive at the Liberty Stadium on Tuesday, 31 January.
Midfielder Joe Allen insists that the win at Villa - Swansea's first away from home - was crucial in giving the team the belief to beat Arsenal.
"It's an incredible feeling and experience [to beat Arsenal]," said Allen.
"[It's] very strange to think that we were very confident we could really get that victory and I think that shows how far we have moved forward as a club.
"We showed great resolve to bounce back and not only get a point but to get all three.
"Confidence is sky high at the moment. I don't think it could get much higher.
"I think we needed that away win. We knew it was coming and we knew it was only a matter of time, but to have gone to Villa Park and got that [win]. I think that gave us the boost we need for games like [Arsenal].
"We are looking forward to keeping our momentum going the way that we have started this year."
