The teenage goalkeeper left Premier League giants Manchester City last summer and was subsequently snapped up by Wrexham.
Wrexham tied him down to a long-term, three-year deal before loaning him out to Colwyn Bay.
Sharpe's progress, though, has not gone unnoticed and now he could be set for a move back to the top-flight.
Swansea are lining up a move for the 19-year-old and could tie him up in the coming weeks.
Garry Monk has already snapped up one goalkeeper this summer, with Sweden international Kristoffer Nordfeldt joining from Heerenveen.
He has been drafted in to provide cover and competition for first choice Lukasz Fabianski, but the Swans are hardly well-stocked in that department and another option – particularly one that can be moulded over time – would be most welcome.
