Celtic's young Hoops (and some more senior stars) disappointed for the under-20s this week.
The young Hoops went 2-0 down after just eight minutes but they fought back to go ahead courtesy of goals from Derk Boerrigter and a Michael Duffy brace.
At that point it looked like there would only be one winner, but Saint Mirren had other ideas and they scored twice including an injury-time winner.
That performance prompted Frail to tell it like it is to a group of players who will be hoping to impress Celtic manager Ronny Deila. However, the defenders in particular had a match to forget.
“I’m really disappointed with the result but more so the performance,” Frail said. “It was a sunny night and I think the players thought it would be easy but it just shows you that it’s not.”
Celtic had a relatively experienced side on display with three first-team players making their way back from injury.
Charlie Mulgrew, Tom Rogic and Derk Boerrigter all started but they could not ultimately inspire their side to a win and it remains to be seen if any of the trio will get chances under Deila before the end of the campaign.
Mulgrew is certainly the most likely to, while Boerrigter’s Celtic future is a little less clear with the former Ajax player struggling for so long with injuries.
Still, for players young and old looking to impress Deila, Frail told it like it was after a performance he will not want to see repeated.
