The 19-year-old, who turns 20 in just over a week’s time and can also play right back, joined Liverpool as 12-year-old and was at Anfield for five years, progressing to the Under-18 side before leaving in the summer of 2012 to join Wigan.
International clearance permitting, he will be available for next Saturday’s game at Barrow to form a new central defensive partnership with Mike Lea.
Jamie Crowther will also be back for that game to bolster midfield.
Wilson watched the Seagulls lose 1-0 at home to Stalybridge Celtic after signing and the manager commented: “He was encouraged with what he saw and is happy with the set up and the club.
“Its a position we’ve needed to fill since Jonathan Royle and Anthony Stephens returned to Wrexham, and we’ve got Mike Lea now to play next to him as a left sided centre half, so we’re happy with that.
“Leggy had to play as a right sided defender today even though he is left footed so that was difficult for him, but once again it was a case of needs must, which is just the way it is at the moment, but he still did well.
“We’ve had to play the last few games with players out of position, supplemented by players from the reserves, who have done well, but if we can get players who are round pegs in round holes then that makes sense rather than having to have square pegs in round holes.”
The Bay’s threadbare squad were again without injured Chris Noone and Marc Williams, and lost to the only goal of the game scored on 21 minutes when Celtic’s Ben McKenna cut in from the left and his shot from the edge of the area beat an unsighted Chris Sanna.
Sanna made good saves from Paul Ennis, Kevin Holsgrove and Scott Kerr, while at the other end Stalybridge keeper Lewis King made an outstanding diving save to turn a Wes Baynes volley round the post and Jordan Bove shot narrowly over the bar.
Colwyn Bay finished the game strongly and King made a fine reflex save to keep out a Louis Moss header from another good Baynes cross and then right at the death Jack Truelove put a good headed chance narrowly over the bar from a Baynes corner.
Gus Williams, of course, knows there is work to be done, but said he was encouraged by Bay’s performance.
“We spoke as a group in training on Thursday and set ourselves some objectives, starting with getting more crosses into the box. We managed to do that (mainly through Louis Moss and Wes Baynes) and created some good chances. Now we need to work on getting on the end of those crosses as the final part of that element of the game.
“We were a yard or two away from the ball today when crosses came into the box, so we need quicker reactions, which is something we can work on.
“But overall it was promising and positive.
“We were looking to play and get the ball down. We need to start doing that with a bit more speed and that is something we can work on week to week.”
Gus added: “I’d like to say a big thank you to all who have come today and supported the Bay. We are grateful for that support, welcome your well wishes and are looking forward to seeing you all again at Llanelian Road.”
Colwyn Bay: Sanna, Taylor, Moss, Lea, Truelove, Haywood, Anoruo, Hodgson (Seddon 66), Hopley, Baynes, Bove. Subs not used: Ollerenshaw, Olapade, Saiel, Mendes.
THE Reserves lost 4-2 at leaders Llandyrnog United after taking the lead through Chris Frost.
Three goals in five minutes turned the game for the home side and they later got a fourth after Ryan Watson had scored Bay’s second.
