The Johnstone's Paint Trophy Southern Area Final sees two rivals go head-to-head as npower League 2 Southend United meet npower League 1 Leyton Orient.
The two sides haven't been in the same division since the 2009/10 season so the Trophy has provided them with a chance to renew acquaintances.
And both teams will be keen to gain the bragging rights over the two legs but, more importantly, earn themselves a place at Wembley in the Final against either Coventry City or Crewe Alexandra.
Leyton Orient are likely to be billed as favourites, as they are currently 13th in League 1, having beaten Stevenage 1-0 away from home last time out.
That result extended their unbeaten run to four matches, and manager Russell Slade wants to see that continued on Tuesday, to give them the upper hand going into the second leg at Roots Hall.
"It's an important game for us, both sets of players, the club and everything because there's a slot at Wembley available and nobody wants to toss that away," Slade explained to www.leytonorient.com.
"It'd be fantastic to win, it's what I want to do, I want to take the fans to Wembley. It's been a big desire since we've got very close to doing so and we're just a contest away from that now and we have to make sure we do it properly.
"The fans were terrific at Stevenage again and we want that especially when it's a local derby. I need them on Tuesday to come out again and get behind the team. It's never easy, the first legs are always tough and if we can take an advantage to their place I'll be delighted."
Southend also won 1-0 in their last match, against Oxford United, and that was their second successive victory.
It left them fifth in the League 2 table, firmly in the promotion mix, and a Johnstone's Paint Trophy victory would keep their momentum going.
Defender Ryan Cresswell is already dreaming of a Wembley appearance, but knows how tough it is going to be against Orient.
He told www.southendunited.co.uk: "I've been to Wembley a few times to watch England games and Play-Off Finals but I would absolutely love to get there and actually play there. There is no need for any extra motivation ahead of this game.
"It's going to be a big test but this squad of players has proved they can compete against League 1 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."
