The Hoops' top goalscorer has not scored in three games for club and country.
Ronny Deila has insisted that he is not concerned about Leigh Griffiths' current form despite the Celtic striker failing to find the back of the net during any of his last three appearances for club and country, the Evening Times reports.
The 25-year-old has scored 35 times in all competitions this season, but failed to add to that tally in his last three outings despite playing the full game against Kilmarnock, almost 80 minutes against Hearts and an hour for Scotland during their friendly with Denmark in between the two Scottish Premiership clashes.
However, Deila explained that his star striker nearly did not feature at all against Robbie Neilson's men on Saturday, before insisting that he has full confidence in Griffiths to score several more before the end of the season.
"Leigh had a bit of sickness because of the migraine but he wanted to play and was hungry to get out there - and he is so important to us that we wanted him to play," he told the Evening Times.
"He has had the problem on Thursday and there was also a little niggle with his calf recently so he has been playing in games without quite being properly fit.
"So I would not worry too much about Leigh scoring goals. He has showed this season how important he is to us with the number of times he has scored and I am sure that between now and the end of the season that there will be at least a few more."
With the former Wolves forward shouldering much of the goalscoring burden this season, Deila will have been extremely pleased that the Hoops were able to win both of their games despite Griffiths' barren spell in front of goal.
With Carlton Cole and Colin Kazim-Richards being the team's only other strikers in the senior squad, the Norwegian may have been concerned about what an injury to their key man would have done to their title chances.
However, the likes of Tom Rogic and Patrick Roberts have stepped up and provided goals from their attacking midfield roles in the last two games, which should send a message to the rest of the top flight that even if they manage to keep Griffiths quiet, Celtic still have plenty of goals in their team.
