There is a school of thought that points to the sight of Leigh Griffiths in a suit and ponders just where the court case is.

The Celtic striker has been black-tie suited and booted more times this month that he has been stripped for action on a football pitch.

Yet, it is a sign of how much the reformed 25-year-old has turns things around off and on the pitch that the formal gear has been dug out to present a good impression to a different kind of judge and jury this season.

Griffiths took to social media to reveal he was “overwhelmed” when he took a trio of awards at the club’s own annual gala dinner, an evening that was followed by the Player of the Year accolade this weekend as voted by his fellow professionals.

More are expected to follow with the SPFWA still to hold their bash at the end of the season.

But as Ronny Deila gets set to quit Celtic later this month, the Hoops boss has insisted that there is still more to come from Griffiths, whoever is managing the player next season. Deila has got the best out of the striker this season, although he has maintained that whoever is coaching the payer needs to recognise what drives him.

“He is an emotional guy and he feeds off of that,” said the Norwegian. “He got angry on Saturday against Hearts, he got booked and then he scored a great goal straight afterwards. His anger has to be controlled and channelled but at the same time you cannot take it all away from him because he lives off of it at times.

“It will be a pity for him if he misses the last game. He has been so important for us this season that to miss the last game is a little bit tough on him.

“But I did not do anything will Leigh. It is not me who deserves credit for the goals he has scored this season. It is down to the player himself. He changed things, he worked hard, he did it all himself and he deserves all the glory he is getting now.”

Kieran Tierney, too, has been labelled one of the success stories of Deila’s reign. The teenager has dominated the Young Player of the Year awards and the Norwegian believes that the defender will keep on improving – because he has the hunger to do so.

And wherever he next ends up, Deila will have a close eye on the players he worked with at Celtic.

“Kieran has to keep on developing next season,” he said. “But he will. I am quite sure of that because he is a boy who just loves playing football and if he keeps that spirit and philosophy then he will keep getting better.

“It has pleased me so much this season to see him improve; when he first came into the team he struggled a little bit with challenges in the air but you can see now that he is getting stronger there. Technically he can still be better but with experience he will be a great Celtic player.

“I will watch him next season because I love to see players getting better. But I love all my players here. I love the club, I love the supporters and I will always look for what they are doing and how the club is doing. That will never leave me.”

Meanwhile, Deila has enjoyed his celebrations this week as Celtic effectively got over the line at Tynecastle last weekend, but the Hoops boss has maintained that he isn’t ready to take his foot off the pedal just yet.

And, despite the low-key response to Celtic’s fifth successive title, Deila has insisted that he doesn’t care if people don’t appreciate its significance.

“I don’t know if we have had the credit we should get for winning the league but I don’t care about that,” he said. “I know that what we have done is an achievement and when you read the history books it will stand as another league title that this club has won and that is the most important thing.

“People can say what they want. It is up to them. But what you find is that there are always people who want to drag you down in football and there are always people who want to build you up. But I have done my best, I can look myself in the mirror in the future and know that I came here and I gave my all.

“I gave it everything I had and devoted myself to the job. It is not my place to say whether it was bad or good but for me, I believe that I gave my best. Where there things I would have differently? Of course there were. But I took a big challenge here, I learned a lot about myself and I can honestly say that I tried my hardest to make it work.

“It has been tough but I have been a happy man this week.”

The Norwegian has his sights set on the exit door but wishes to go out on a high.

the Hoops play Aberdeen this weekend, a team who have beaten Celtic twice and pushed them for far longer than many would have anticipated.

“I would like to maybe have a look at one or two younger players because there are a few players in there who have caught my eye,” said Deila. “But also I want to win these last three games. I don’t just want to play them out now, I want us to win by playing the way that we did against Hearts.

“We have a game on Sunday against Aberdeen to look forward to and we will go into it on the back of a good week. I want us to produce the same kind of energy and fight that we showed against Hearts. I don’t want to stop now.”
