Kris Commons has urged Celtic to stick with Neil Lennon despite the Hoops' recent run of poor form.

Celtic crashed out the Europa League last night as they suffered another shock defeat to Sparta Prague.

The 4-1 thumping piled pressure on Lennon after the Green Brigade called for him to be sacked earlier this week.

But for ex-Parkhead striker Commons, his old side must stick instead of twisting with so much on the line this campaign.

He told talkSPORT: "I think they have got to stick with Neil Lennon.

"I've been in a dressing room with Neil as a manager and a player, he is a natural leader and a born winner. He knows Celtic inside out.

"He's the gentleman that enlightened me on everything about Celtic and what it stood for and what it meant to be a Celtic player.

"So for me, he is the right man in the job.

"I think he's been let down considerably by the players he's picking, particularly the defence.

"I think the board have stuck by Neil in terms of the money they spent on defenders.

"But I'm not convinced that any of these signings are doing Neil Lennon any good.

"Barkas, £3million. Christopher Jullien, £7m. Boli Bolingoli, £3m. Elhamed, £1.6m. Shane Duffy who will be on massive wages considering the rest of the squad.

"The goals that they've conceded are quite frankly ridiculous. They've only played four games in the Europa League and they've conceded 13 which is a crazy amount of goals.

"In the league, St Mirren have only conceded two more goals than Celtic and they sit second bottom. Two more goals.

"They're not joined as a whole, they're not united as as team. It leads me to think that they are playing as individuals, that there is players in that dressing room that are not willing to run the extra 10 yards.

"They're not wanting to be there, they don't care about Celtic."
