Ryan Christie insists no one at Celtic is panicking after their 2-1 defeat at Kilmarnock on Sunday confirmed their worst start to a Ladbrokes Premiership season in 20 years.

Former Hoops youth defender Stuart Findlay headed in a dramatic added-time winner from a Chris Burke corner after the veteran winger's drive had cancelled out Leigh Griffiths' first-half opener.

The champions have amassed only 10 points from six league games ahead of the Betfred Cup quarter-final against St Johnstone at McDiarmid on Wednesday night, where Christie hopes to get back on track.

The 23-year-old forward, who started his first league game for Celtic this season in a rejigged Hoops side, said: "It is just about belief and togetherness. We know we have got that.

"We are starting to come under a bit of scrutiny, but that is when you start looking to either side of you, at your team-mates and push each other through.

"We have definitely got the ability to do that. We are not exactly panicking or anything like that.

"We still highly believe that we can push on and get back to the top of our game and we are looking to do that as soon as we can.

"Now we go into the St Johnstone game and we are desperate to put ourselves into a semi-final.

"Everybody has to be at the top of their game. We have to forget about yesterday, look at it and right the wrongs.

"But most importantly focus on St Johnstone and make sure we come out of that having progressed into the semi-final."
