Celtic Under-19s coach Willie McStay is backing a number of his double-winning squad to graduate to the senior side.
The Parkhead youngsters added the Youth Cup to the championship trophy after an epic and nervous struggle against Hearts at Celtic Park last night.
Michael McGlinchey and Mark Millar struck late extra-time goals to clinch a 3-1 success after John Neill had cancelled out Theodor Bjarnasson's opener.
The likes of Scott Cuthbert, Darren O'Dea, McGlinchey and Simon Ferry have flirted with the first-team squad and former Celtic star McStay believes they and others could make the grade.
The former Sligo Rovers player/manager said: 'The scoreline might have been flattering but in football, moments of quality win matches and that's what happened. This means everything to them and it caps off a fantastic season.
'It is a great honour and great recognition for them to win the Scottish Youth Cup and the championship in the same season. These players now have to make that step up but I am convinced they can do that.'
McStay, who won an amazing Shield, First Division and FAI Cup treble with Rovers in 1994, continued: 'Charlie Grant was immense having played the captain's role perfectly. He is definitely one for the future.
'Simon Ferry did smashing, as was Darren O'Dea, but let's not take anything away from the others. There are some good players here. They can make an impact here at a higher level and it's up to them to do that now.'
Hearts coach Stephen Frail felt his side deserved more from the game.
He said: 'Let's take nothing away from Celtic - they have been consistent over the season and that's why they have won the league and cup. But in my view we were much the better side and we deserved more than we got.
'Sometimes football works like that and these players have to take it on the chin and come back from this.'
