Noel Whelan has suggested the Celtic board could sack Neil Lennon before Christmas if he fails to turn things around over the coming weeks.

Speaking exclusively to Football Insider assistant editor Russell Edge, the former Aberdeen striker has admitted it looks like the Bhoys “downed tools” in their European fixtures this season.

As revealed by Football Insider, the Celtic board have no plans to sack the Northern Ireland manager at the moment and are likely to hold fire until at least the derby clash with Rangers on January 2nd.

The Bhoys are currently 11 points behind their Glasgow rivals in the Premiership table, albeit having played two games less than Steven Gerrard’s men.

Celtic also saw their hopes of qualifying for the Europa League knock-out stages crushed on Thursday with another 4-1 defeat to Sparta Prague.

Whelan has admitted he thinks Lennon is safe for now but admitted things could be very different if things do not change in the early stages of December.

Whelan told Football Insider: Well, I think right now they’ll probably put the faith in him and give him an opportunity to see if he can turn these really inconsistent performances and around right now as you would expect them to go on when the majority of their League games.

“You would expect them to go and win the majority of Premiership games, you would expect that. It’s the Europe side, they’ve been so poor this year and it’s like they’ve just downed tools and looked weak and not even competitive against certain teams which usually they would be steamrolling over.

“I think that’s the problem, the longer you go through in the European leagues the more you get out of it financially and, as a club, as the stature of a club, as a European club. Right now, they’ve looked way off pace.

“I think I think he needs to turn something around quickly. If it doesn’t turn around quickly performance-wise in the Premiership, I can see a change before Christmas.”

Celtic have picked up just one point from their four Europa League group stage games after a 2-2 draw with Lille in France.

They have been beaten by Sparta Prague both home and away, while AC Milan left Parkhead with a 3-1 win in the Bhoys’ opening game.
