Having extended his loan deal at the Proact until the end of the season, Declan John is expected to progress even further by Spireites manager Danny Wilson.
The 20-year-old has appeared in five games for the Spireites so far, making a big impact as his new side have found form in recent weeks.
Wilson spoke about the Welshman's energy and flexibility during a time when the squad is otherwise depleted down the left flank: "It's a big bonus for us that he's agreed to stay and that Cardiff have allowed him to.
"It's important for him to be playing and being part of the squad and that's great for us, particularly with the situation that developed over the weekend with Dion (Donohue) being suspended and Dan (Jones) with the blow that he's going to be out for another six weeks or so.
"The lovely thing is that he's quite flexible in where he can play; he can play in front of a left-back, or he can be the left-back. We'll see what's in front of us and we'll see where's the best option for us to utilise his talents."
Twice capped by the full Wales side, Wilson feels that his role with the Spireites could open the door for John to squeeze his way into Chris Coleman's squad this summer as the Welsh head to their first major tournament since 1958 for Euro 2016.
"Being here can only do him a power of good," said Wilson of John's international prospects. "He's playing 90 minutes in games in a very tough lead. That Always will count for a lot when you're looking to get picked by your international team.
"When you're playing under 21 football all the time and it's intermittent that could possibly go against you, so it's a positive move for him.
"Hopefully, from our point of view, we can give him the platform to step up to that."
