Fleetwood Town spent lavishly in a bid to continue their Wimbledon-esque ascent up the English football pyramid, and begin their bid for a trip to Wembley at Bootham Crescent on Saturday.
One day later, Burton Albion host Southend United in the division's other semi-final first leg – eight days after their 'dress rehearsal' on the final day of the regular season dictated which of them would have home advantage in part two of their duel.
York won 11 and drew six of their last 17 outings – a run that began with a 2-1 victory at Fleetwood at the start of February.
"They are the Manchester City of our league with a wealthy chairman who has spent money, so we will need to be on our best behaviour," warned Worthington.
"But if we go out and perform, we have got a good chance of getting into the final."
The performances on two on-loan 22-year-olds could be crucial to the outcome. York's fresh-faced goalkeeper Nick Pope and Fleetwood midfielder Josh Morris – on loan from Charlton Athletic and Blackburn Rovers respectively – were nominated for League Two's Player of the Month award for April, with the latter emerging triumphant.
"Home first is what we would have chosen so I'm pleased and now we have to make sure that we're as positive as we can be," said the former Derby County defender.
Southend finished the season with 19 points from a possible 24 and the division's best defensive record. Goalkeeper Daniel Bentley, 20, and 21-year-old midfielder Ryan Leonard were both excellent for Phil Brown's side, while towering striker Barry Corr has netted five goals in his last six games.
"We're going in to the play-offs with a winning mentality and I think that's vitally important," said Brown.
"We have a fantastic defensive record and in Barry Corr we have a striker in a rich vein of form."
