Noel Whelan suggests that Celtic striker Leigh Griffiths could seal a transfer away from Parkhead after the “embarrassment” of returning to training unfit.

The former Leeds and Aberdeen striker, speaking exclusively to Football Insider assistant editor Russell Edge, insists the 29-year-old has “shot himself in the foot” after letting Neil Lennon down.

As quoted by Sky Sports, the Hoops boss ripped into the striker for his indiscretion and insisted that “he wants to have a future (at Celtic), it’s down to himself.”

Whelan believes that while other clubs might be willing to sign him this summer, he will rue the chance he has passed up at Parkhead if he leaves.

“I don’t think it’ll stop him getting a club because we know he’s still a very good player, what it will do is take him away from one of the biggest clubs in Scotland and in Europe,” Whelan told Football Insider.

“What it has done is shot himself in the foot because at the back end of last season he was banging in goals, looking very, very sharp and more like his old self. You’d think he’d carry on that form, you think you’d want to keep your body in a good place after what’s gone on in your head.

“Fitness can be the one thing that takes your mind off all these other problems by throwing yourself into it. Unfortunately, he’s really let himself down here and Neil Lennon, hence why the embarrassment of being left at home.” 

Griffiths scored 11 goals in 31 appearances last season, with over half of those strikes coming after the Premiership’s winter break.

He has a total of 234 games under his belt for the Bhoys, as well as 19 caps for Scotland.
