Matty is very much the surprise package of the season to date having come from almost nowhere to challenge for the right back starting berth in the Swans Championshop challenge.
And whilst he may be some way from ousting Angel Rangel as first choice right back, Collins almost certainly seems to be ahead of Alan Tate in the rankings meaning he will deputise for Rangel at the Valley tomorrow.
And Collins is revelling in a change of fortune from last season when he spent time at Wrexham on loan as they battled unsuccessfully against relagation to the Conference. He told today's Evening Post "The manager hasn't really given anything away about what the side's going to be, but hopefully I might be involved
"I've worked hard over the summer to give myself a chance and I've been pleased with the way pre-season has gone. It would mean a lot if I was part of the side at Charlton.
"Last season was frustrating for me because like everyone else I wanted to play. But I've seen other players in that position spit their dummy out.
"They haven't shown the right attitude and they've been tossed aside as a result.
"But I got my head down and worked hard and I feel like I'm starting to reap the benefits now.
"The manager says he sees me as a right-back now," Collins adds.
"I played there a few times for Fulham so I knew the basics of the position, but the manager has helped me a lot with the defensive details.
"Things are starting to come naturally to me now and I'm enjoying being a right-back.
"Angel did fantastically there last season and Tatey is a very good player, but the competition benefits everyone.
"I feel like I'm improving every day and I'm confident I can do well for Swansea in the Championship.
"I played at The Valley for Fulham's reserves a few years back," he recalls.
"I think there were a few hundred fans there maybe, so tomorrow will be a bit different.
"It doesn't come much bigger than Charlton away in this division, but I'd love to be involved."
