KRIS COMMONS believes Leigh Griffiths could have been heading to France with the rest of the Celtic squad - if he had focused on his fitness instead of making TikTok videos during lockdown.

Scotland international Griffiths did not travel with the Hoops to their training camp in Loughborough and will now miss out on matches against Lyon, Nice and PSG due to fitness issues meaning he was left to work on his own at Lennoxtown.

And his former teammate Commons reckons he only has himself to blame.

Speaking in the Daily Mail, he said: "Clearly, Lennon feels Griffiths was over-indulging during lockdown.

"Listen, I dare say we can all relate to that. We've all put on a couple of pounds.

"That's fine for your average man in the street, but not for a Celtic striker entering one of the biggest seasons in the club's history.

"The accusation from Lennon is that there has obviously been a lack of professionalism on Griffiths' part if he's returned for duty out of shape.

"Knowing Griffiths as I do, I can tell you right now he won't have been tuning in to the Joe Wicks videos every morning.

"He's always been very laid back when it comes to training. He's not a Callum McGregor-type figure, who is first in the building every morning and the last to leave.

"Griffiths is a maverick. But the reality is that he's playing a very dangerous game because he's now needlessly thrown his future at the club into doubt.

"Given the enormity of the season ahead and the chance to clinch the Holy Grail of ten in a row, it feels like he is blowing the opportunity of a lifetime.

"Celtic fans would give their right arm to be in his shoes; to be the man who scores the goals to lead the club to such a legendary achievement.

"If Griffiths has indeed returned to training badly out of shape, then that won't sit well with supporters. It just won't wash.

"The club have backed him through thick and thin over these past few years. But it feels at times like he's his own worst enemy."

He added: "What also doesn't help his case is the fact that he's been posting all of these daft videos on social media recently.

"If he'd focused half as much effort into his fitness as he has done posting TikTok videos during lockdown, then he'd be flying around Lennoxtown like Usain Bolt.

"But, right now, there's a genuine danger he's going to head into the new season as the club's fourth-choice striker.

"Odsonne Edouard, Patryk Klimala and Vakoun Bayo are all ahead of him in the pecking order at this moment."
