The Shrimpers travel to League One Leyton Orient for the first-leg and the 25-year-old defender is confident his Wembley dream can become a reality, providing they are still in touch by the time of the return game.
He told the club's official website: "Everyone dreams about playing at Wembley and scoring the winning goal. We have spoken about it but the main focus is without doubt the two games against Orient.
"It's going to be a big test but this squad of players has proved they can compete against League One sides and on our day we can beat them, so we will go into the games confident.
"What's most important is that we are not out of the tie by the time the game comes to Roots Hall.
"We want to win, but the tie can't be won after the first leg. It can almost be lost though."
