Celtic ended their home season in style and reminded their long-suffering supporters of the kind of performance this side is capable of producing with a clinical first-half demolition of lowly Colwyn Bay.
The scoreline was no reflection of Celtic's dominance in this game as they could and should have won by a margin which would have put Worksop's 9-0 drubbing of Winsford to shame. But, as so often this season, Celtic failed to convert their chances and the visitors from Wales were spared their blushes.
All the goals were scored in the opening half hour with Celtic getting in on the act first. Stuart Gelling handled a Steve Pickford cross and Eddie Johnston proved a more than capable deputy for Gary Bauress when he coolly sent Roberts the wrong way from the penalty spot.
Three minutes later it was two when Tony Sullivan turned the unfortunate Gelling inside out before curling a beauty into the top corner from 20 yards. Colwyn Bay were visibly wilting and when man-of-the-match Kevin Parr lashed home from 15 yards on 23 minutes, a rout looked on.
However, Celtic relaxed and allowed Bay to pull one back when Marc Limbert hit a superb free-kick past the statuesque Ingham from 25 yards.
The second half saw Celtic continue to run their opponents ragged with wave upon wave of attacks. It would be impossible to list all of Celtic's chances, but Parr hit bar and post with headers, Fairhurst cleared off the line from Sullivan, and Roberts denied Scott (twice), Crossland, Pickford and Sullivan with fine saves.
