Celtic boss Neil Lennon wants to help bring through the young players at Parkhead.
Dembele, Henderson and Johnston were all offered game time at Celtic towards the end of last season, and seem to have forced their way into the Bhoys’ first-team squad now.
Johnston even was selected to play in Celtic’s cup final against Hearts, which they won 2-1 at Hampden Park.
And Lennon admits that he thinks that the trio of academy graduates can play big roles at Celtic in the future.
“I am excited about them,” Lennon said. “Dembele lit the place up the other week. He is very important to the club, as are the likes of Henderson and Michael Johnston, who played in the Cup final.
“That will be a huge shot in the arm for Mikey. We think he’s good enough. It’s important for me as a manger to bring players through from the academy. It’s vital we develop our own.”
Dembele, in particular, looks like a very exciting prospect for Celtic, with the 16-year-old making a huge impact on debut.
Celtic brought on Dembele at half-time in their final game of the campaign against Hearts, and his display at Parkhead really excited the home crowd.
Dembele could feature far more regularly for Celtic next season, if Lennon does stick with his commitment to bringing through young players.
