Cahill said: “Everyone knows what I think of Tommy, I'm a big fan of his. But I want people to let him play, let him enjoy his football and take the pressure off him. [Coming back from] long-term injury, it's going to take a season for him to be in full flow and back firing properly.”
Rogic, 22, has truly established himself at Celtic this season after doubts about his ability to play for the Bhoys, with 17 games and five goals to his name this term.
He has grown more and more into a first-team starter as the season has progressed, and is now one of the key players in Ronny Deila’s Celtic side.
This is the first time Rogic has truly established himself at Celtic, having been struck down with a constant groin injury after he signed for the Bhoys at the beginning of 2013.
However, he is now back and looks to be at his best, but Cahill has urged fans not to increase the pressure and expectation on Rogic’s head after such a short run of good appearances.
The Everton great wants to see fans - both Celtic and Australia - continue to support Rogic in his development, as Cahill does not believe the youngster is still at his best, as he is still on the recovery from his injury.
Rogic has shown this season that he can live up to the qualities that were expected of him, and if he does continue to develop as he has been, Celtic have a truly top class player on their hands.
