James Gibbons says he is not satisfied with his current form, but the defender is confident he can recapture it ahead of Vale's clash with Swindon Town on Saturday.
Gibbons has admitted he's struggled to reach the standards he was at prior to his four game ban in December, after being sent off against Yeovil.
The full back has featured in every game since returning from suspension, but is still disappointed with his performances.
"I've got my place back in the starting eleven, but I'm still not happy with how I'm playing.
"I hit a good run of form, but I haven't been able to find it again after my suspension.
"I don't think the red cards have had anything to do with it. I've learnt from them both, and I haven't done anything stupid since.
"I think I'll get the form back though, with the more games that I play. For whatever reason, sometimes my distribution's off, but I'll get it back."
However, despite his recent performances, Gibbons believes he has progressed a lot as a player since debuting for the Valiants in September.
Gibbons has found himself to be a regular under Aspin since his debut, and believes he's still learning every day.
"I feel like I've developed massively. At training sessions when you've got all the lads round you, the more experienced ones are always talking to you.
"I'm only 19, so if you look at it that way, you can only get better."
