Former Celtic midfielder Kris Commons has questioned his old club's recruitment strategy, as he called on Patryk Klimala to demand more game time.
The Parkhead club were eliminated from the Champions League by Ferencvaros on Wednesday, with manager Neil Lennon rounding on his players as he insisted some were trying to engineer transfers.
But Commons insists it's just not just the attitude of Celtic 's stars that's a problem - he sees a lack of quality in the squad as a whole.
And the former Scotland international says he'd be beating Lennon's door down if he was in the shoes of Polish striker Klimala, who didn't get off the bench against Ferencvaros.
Commons wrote in his Daily Mail column: "It's not just the attitude of certain players that's concerning right now. It's their quality.
"The most fundamental thing about football is you are only as good as your striker.
"Odsonne Edouard is a phenomenal talent but he's only one player and Celtic are now over-reliant on him.
"When I was there you had a Greek international in Georgios Samaras, Gary Hooper and Anthony Stokes. This feels like slim pickings in comparison.
"Aside from Edouard, there's no one in that team now who'd be guaranteed to get you double figures for the season.
"I could understand Albian Ajeti not starting against Ferencvaros as he hasn't played a lot of football but Patryk Klimala has been there since January and has had a full pre-season.
"Yet an attacking midfielder in Ryan Christie started ahead of him. That's a trust issue which is worrying.
"Maybe the player doesn't feel quite ready. But if I'm in his shoes, I'd have been into Lennoxtown at dawn yesterday to ask the manager why I'm not getting a game."
The former Celtic man also questioned the club's recruitment under Nick Hammond, insisting his transfers have been more miss than hit.
Commons said: "I just don't think they've spent their money as wisely as when John Park was there.
"Yes, he messed up a few but he found some gems — Van Dijk, Fraser Forster, Victor Wanyama, Joe Lesley.
"Aside from Edouard, who's come through the door recently who's made a big impact? Christopher Jullien at £7m? I'm not convinced. Boli Bolingoli? Not good enough. Vasilis Barkas? I'll need to see a bit more. Greg Taylor? I don't think he's European standard. Hatem Abd Elhamed — no. And Jeremie Frimpong is a kid.
"Where's the last one who you know will go for big money and will be a top player for as long as they are there? The old guard — Brown, Callum McGregor and James Forrest — are having to keep the bandwagon going. You need two or three Edouards a season. Not one every three years."
