Frank McAvennie has urged Leigh Griffiths to “get his head right” and force his way into the Celtic side after his bust-up with Neil Lennon this month.

The Parkhead legend, speaking exclusively to Football Insider, suggested a fallout between player and manager prevented Griffiths, 29, from a consistent spell in the side.

Lennon resigned as Celtic boss on Wednesday morning with the club 18 points behind Rangers in the Scottish Premiership.

Over the course of the season he was questioned for his decision to snub Griffiths, with Lennon claiming, on numerous occasions, the Scotland international was not fit enough.

Griffiths has not started since the 2-1 loss at St Mirren last month when McAvennie claimed he had a bust-up with Lennon at half time that day.

When asked by Football Insider if Lennon’s departure could result in more game time for Griffiths, McAvennie, who lives in Glasgow and is well connected at his old club, said: “It might but we just do not know what is happening with Leigh.

“He is an enigma. Why he was not playing I do not know. Did he not get on with Lenny? He never got many games. I just do not get what is going on.

“He is a great striker, the best finisher we have got a the club.

“He has to get his head right though and hopefully he’ll get a run of games.”
