Alex McLeish has urged John Kennedy to give Anthony Ralston a run in the Celtic XI until the end of the season.
The former Scotland boss, speaking exclusively to Football Insider, suggested the Bhoys need to make a “massive assessment” of the 22-year-old ahead of next season.
Everton loanee Jonjoe Kenny has been Celtic’s first-choice right-back and has played every minute since joining in January.
However, it remains to be seen whether the 24-year-old will return to Parkhead at the end of his temporary spell.
Ralston’s only appearance this season came in a 0-0 draw with Livingston in January before Kenny’s arrival.
He has been a regular among the substitutes’ bench, however.
McLeish admitted there must be a reason for Neil Lennon and John Kennedy not to have picked the youth graduate.
However, with little to play for but pride, he suggested Ralston should be given a run to see if he is good enough for next season.
“Ralston, his name keeps cropping up and it has done for over a year now, maybe even beyond,” McLeish told Football Insider assistant editor Russell Edge.
“There’s obviously something that the managers haven’t quite liked in terms of playing him consistently. You have to let these kids breathe and make mistakes.
“But at Celtic, clubs like Celtic and Rangers, where you have to win all the time, that’s when it becomes more difficult a decision to make for the coaches and managers.
“Ralston, they should try and give him as many games as possible, I would think, to make a massive assessment.
“To maybe say this kid has got to be one of the kids going forward. Much like young Welsh has shown with his form this season.”
