Celtic should trigger the one-year contract extension included in Leigh Griffiths’ current deal.
That’s according to former Celtic striker Frank McAvennie, speaking exclusively to Football Insider about Griffiths’ future.
As reported by the Scottish Sun, Celtic have until the end of the month to trigger a one-year extension clause worth £1million in Griffiths’ contract.
If the clause is not triggered then it is likely Griffiths will leave Parkhead for nothing at the end of the season.
McAvennie insists that Griffiths is still the best finisher at the club and claims that Celtic’s fitness coaches need to work harder to keep him fit.
“I don’t know what’s going on with Griff,” McAvennie told Football Insider correspondent Ben Wild.
“You’ve got people coming out of the club saying that he’s not fit but the club have a huge team of fitness coaches and you’re thinking, ‘surely that’s your job’.
“You would think, they’ve got half a dozen fitness coaches. You would think that one of them could get him fit.
“Maybe I’m thinking outside the box too much. He’s the best at the club in terms of shooting and finishing, if it’s just down to football they should give him a new contract.”
Griffiths, 30, has scored seven goals in 24 games this term, including a last-minute equaliser against Aberdeen last week.
Celtic travel to Ibrox on Sunday as they look to register their first win against Rangers this season after losing three and drawing one of their other Old Firm clashes this year.
