Arsene Wenger revealed that he had a talk with Hull City players, following their FA Cup triumph at the Wembley last year, who said they were mortified by the prospect of Arsenal throwing in the likes of Jack Wilshere and Tomas Rosicky in extra time.
The Gunners had gone 2-0 down in the opening 10 minutes, but managed to come back into the game with goals from Santi Cazorla and Laurent Koscielny on either end of the two halves, while Aaron Ramsey scored the winner to end Arsenal's nine-season trophy drought.
Wenger has all the players at his disposal along with Theo Walcott, who could not feature in the finals last year with an anterior ligament cruciate injury. The manager has a selection problem between Walcott, who scored a hat-trick against West Bromwich Albion and Olivier Giroud, who has not managed to hit the net in his last seven games in all competitions.
Giroud provides a physical presence up front while Walcott can run the Villa defence awry with his blistering pace, a good dilemma to have for Wenger. The Gunners also have Alex Oxlade-Chamberlain on the bench to provide a different option should they be in need of goals.
"The whole squad has to focus on doing it as most of the time the heroes are the guys who come on. I remember last year in extra-time I brought on [Tomas] Rosicky and Wilshere. After, I spoke with the Hull guys and they told me: 'When we saw them coming on, we knew that we didn't have a chance any more.' Most of the time it is a squad achievement, a cup final," Wenger said.
"I was thinking that it was a nightmare day. All the fans came full of hope and we are 2-0 down. It could have been three as [Kieran] Gibbs saved on the line. With the pressure on it was really a nightmare.
"I was ready for a fight. I was ready to fight until the end. You knew that you need a goal and certainly the free-kick of Santi Cazorla was very important. After that it was important to keep the players calm and not rush the game. Just be patient, come back to 2-2.
"We have learned a lot from last season and let's show that on Saturday," he continued.
