Ronny Deila has told the Glasgow Evening Times that he is pleased with the development made by James Forrest this season.
Forrest has faced criticism from Bhoys supporters in the past, but Deila believes that the 23-year-old has shown signs of progress.
Although the Norwegian boss admits that the skilful winger needs to become more consistent if he is to fulfil his potential, he still has high hopes for Forrest's future at Parkhead.
"I have seen a big improvement in James and he has also started to really work hard and show the same kind of consistency in training," he said.
"It is good to see because we know that when he is at the top of his game that he is such an important player for the team but we need that consistency."
Forrest has been tipped for stardom ever since making the breakthrough at Celtic, but he has been stuck with a ‘promising’ tag for too long.
At 23, Forrest is now reaching an age where he should be a first-team regular, rather than a promising hopeful, and Deila's words about him finding consistency will need to be heeded if he is to push on.
At the moment Forrest can look anonymous in some matches, while he can be a match-winner in others, and that has frustrated Celtic's supporters - who want to see him show the same level of commitment in all fixtures.
With Deila backing him, Forrest has an excellent chance to fulfil his potential, and the 39-year-old boss will be hoping that his faith in the academy graduate pays dividends over the coming years.
