Paulo Di Canio has urged Swindon not to think about Wembley after their 2-1 Johnstone's Paint Trophy semi-final win at Southend.
Swindon have now booked their place in the Southern area final of the competition.
Goals from Paul Caddis and Ronan Murray set up a showdown with Barnet, who beat Brentford 5-3 on penalties in the other regional semi, after Blair Sturrock put Southend ahead.
However, Di Canio is focussing on league matters.
"Southend are top of our league and this was our first real challenge," he said.
"But I have told them that it is enough celebrating and now we must think about the league.
"I said forget what has happened tonight (Tuesday), but keep the best from this match and keep it going in the league."
