The Gunners drew 2-2 at the Liberty Stadium in the third round last week and now get the chance to redeem themselves for that result, and the weekend's loss to Manchester City, by putting in a positive display at the Emirates Stadium.
"Looking at the Swansea game in its entirety, I think we deserved to win. We had plenty of chances and I don't think anybody could have complained if we had gone through to the next round," Vermaelen said.
"At 2-1 up that late in the game, you would like to see it through. It is never nice to concede in the final few minutes, but we will look forward to the replay and feel that our FA Cup destiny lies in our own hands."
