Speaking exclusively to Football FanCast, Frank McAvennie has told current caretaker manager John Kennedy that he must "liven up" and admitted the Celtic job is "too big" for him.

Kennedy joined the Hoops as first-team coach back in 2014, and has worked under Ronny Deila, Brendan Rodgers and Neil Lennon before being put in temporary charge following the latter's recent sacking.

The former Scotland midfielder, who has remained unbeaten in his four games in the dugout, including the Old Firm draw with Rangers last month, is currently second-favourite behind former Bournemouth manage Eddie Howe to succeed Lennon.

Kennedy looks set to remain in charge for Celtic's final five Scottish Premiership fixtures, and he'll be desperate to salvage some pride and ensure the Glasgow giants avoid their first trophyless season since 2010 by winning the Scottish Cup next month.

But McAvennie has advised Kennedy to earn his stripes as a manager in the lower leagues before considering a job the size of Celtic.

He told Football FanCast:

"No disrespect to John, I think Celtic is too big a club. Neil Lennon done it, but Neil was such a legend. And he had that behind him, so the fans gave him time, but they won't give John time because he's not held in the same regard.

"I think he might be a good manager, but I don't know him well enough to say what his persona is, but he has got to liven up. If you walked into a dressing room, I wouldn't be inspired, I would want someone to come in and fire me up.

"I think he might be a good manager, but he's seen off four managers. I would think it's time to go away, do something different, manage a lower league team, like Hamilton, Dundee, Dundee United. You're going to get time at other jobs, but you won't get time at Celtic."
