The teenage defender has been impressing for the development side.
Some of the Celtic youngsters have certainly impressed in recent weeks. 18-year-old Kieran Tierney has become an integral part of the Celtic first-team and Callum McGregor is now beginning to establish himself in the first-team. Joseph Thomson has also recently made his first-team debut at Celtic Park.
“The pathway to the first-team is becoming more accessible with the likes of KT (Kieran Tierney) and Joe Thomson, who’s made his debut for the first-team too, so we know it’s there for us and games like this are the ones where you want to show you can make that step-up.
“John Collins and the gaffer have been there at the last few UEFA Youth League games as well so it’s great if they can see we can do it at that level, and it gives us even more of an incentive to get involved at first-team level."
Kelleher, whose younger brother is a goalkeeper in the Liverpool youth system, has been impressing for the Celtic youth teams in recent times and is the current Development Squad captain.
The talented defender is in action tonight in the Premier League International Cup against Chelsea where he will be hoping to impress and get his name on the radar of Ronny Deila and the first-team squad.
Kelleher has been on the bench for Celtic once this season, against Dundee United in August, but is still waiting for a new call-up to the first-team picture.
Celtic fans will certainly be hoping to see yet another talent come through the ranks and Kelleher might just be that man.
