Celtic have gone backwards since the departure of Neil Lennon says former Parkhead man Kris Commons.

After yet another poor Old Firm performance yesterday - the sixth game in a row the Hoops have failed to win against their fiercest rivals - Commons has torn into his ex-club.

Celtic have been under the interim management of John Kennedy since Lennon resigned at the end of February.

HeraldScotland:

And Commons has not been impressed with 37-year-old since he has taken over.

Writing in his Daily Mail column, the former Scotland international made it clear that things are as bad as they have ever been. 

He said: "This was billed as a chance for Celtic to salvage a little bit of pride at the end of a painful, fractured season in which they have stumbled from one disaster to another.

"Celtic went out with a whimper, unable to rouse themselves and show the levels of passion, fight and commitment that the badge on the jersey demands of them.

"As soon as Callum McGregor was sent off yesterday, you knew exactly what was going to happen. There was a sense of inevitability to it all.

"In the end, it felt fitting with what had gone before that it should end in embarrassment at the hands of Rangers."

HeraldScotland:

Kennedy has now only won three out of his eight games in charge, leaving his chances of landing the job permanently being very slim.

Commons feels this record is not good enough and went on to describe the differences between this current team and the squad Brendan Rodgers assembled.

He continued: "Just over three years ago, Celtic travelled to Ibrox and went down to ten men when Jozo Simunovic was sent off for an elbow on Alfredo Morelos.

"Despite being a man down, Celtic went on to win 3-2. They were a supremely well-coached team bursting with talent, confidence and, most importantly, pride in the jersey.

"This current team is nowhere near that sort of level. It's now well over two months since Neil Lennon left the club and things haven't improved in the slightest.

"In all honesty, they're actually even worse now than what they were a few months ago. The slide has continued unabated and they are now in one almighty mess."

Commons then went onto criticise the mentality of certain players at the club and also the lack of money Celtic will be able to demand for their prized assets.

He continued: "Celtic are now no longer in a position to command top dollar for their assets. Edouard will leave the club in the summer for a vastly reduced fee than the £25-30million he would have been worth 12 months ago.

"The same applies to Ajer. I actually thought there was a chance he might stay next season, but his performance yesterday forced me to revise that opinion. In his own mind, he's already away.

"The way he turned his back on the ball the absolute cardinal sin for any defender when he had a chance to block Morelos' shot prior to him scoring was embarrassing.

"With Champions League qualifiers for next season now just 12 weeks away, Celtic are wasting time when they simply cannot afford to do so."
