Noel Whelan has claimed it is clear there’s been another Neil Lennon-Leigh Griffiths bust-up at Celtic.

The former Aberdeen and Leeds United striker, speaking exclusively Football Insider, admitted he thought the Scotland international had redeemed himself at Parkhead before falling down the pecking order once again.

Whelan believes the Celtic hitman may have fallen out with manager Lennon once again and insisted the “rift” could be impacting the rest of the squad.

The 30-year-old started seven times in nine games over December and January but was hooked at half-time against St Mirren, left unused against Kilmarnock and featured as a substitute in the win over Motherwell.

Griffiths has been in the spotlight at Parkhead for the wrong reasons for much of the campaign, starting when he returned to pre-season training overweight and out of shape.

Having returned to the side in October, he was then instructed to get fitter by Lennon at the start of December, before being told to work harder for his place in the side just weeks later.

“He was doing so well for a period, playing, scoring the goals, getting all kinds of different goals, then all of a sudden, again, something crops up,” Whelan told Football Insider assistant editor Russell Edge.

“We don’t know what it is but again, like Gareth Bale, there’s a reason why you’re sitting on the bench, there’s a reason why you’re getting hooked.

“Only Neil Lennon and Leigh Griffiths know why but we know there was a rift before the season (about Griffiths) coming back overweight, we knew there was an issue there.

“Then he won the heart again of Neil Lennon and now, again, it looks like there’s something between them that’s just not right and there’s been some kind of bust-up.

“You can’t be having these little rifts within a squad or with a manager, it’s not healthy for everybody else and around them.”
