Having scooped the PDL2 North title last season, the Owls Under-23s are within one point of retaining their crown.
On Friday, the Wednesday youngsters host Burnley at Hillsborough and Under-23 coach Neil Thompson has challenged the players to rise to the occasion.
“It’s a given that they can play the game because they are here and are professional footballers or scholars at the end of the day,” he told swfc.co.uk.
“They’ve all got the techniques but the skill of it is doing it on demand when it matters and when the pressure is on.
“It’s about the character of the players. You have thousands of decisions to make during a game and more often than not, you have to make the right ones, that’s what being a player is.
“The lads have done great in the last two seasons, shown a lot of character, a lot of spirit. They have dug out results when we have not looked at our best.
“Who knows what Friday brings.”
Wednesday go into the game one point behind leaders Bolton, who have now completed their league fixtures.
Thompson continued: “Even if we draw, we get the title but we have got to look to win the game and be very positive.
“There is something at stake for us.
“We’ll do the same preparations, the games have come thick and fast but we know the drill.”
Fans are welcome to support the Under-23s on Friday at Hillsborough (1.00pm), with free admission for Season Ticket holders, £3 Adults and £2 Concessions.
“We know last year when we got to the play-off stage, the support we had at Hillsborough in the semi final and final was fantastic,” he said.
“This is a little bit different, it is a league game but we might have the play-offs to come as well.
“But we are looking ahead just to this game and the supporters would really give the lads a boost.”
