Invincibles driven by fear of failure

going in training and in games, working the same way and showing the same focus which is instilled by the manager.

“Right now, we don’t really think about it. We just go out there to try and get the three points. Nothing else really comes into our heads, about being unbeaten or anything like that. We just try not to lose.

“Of course, the manager here is great. He wants us to do certain things but he also wants us to use our imagination and creativity.

“That’s where our best football comes from, just playing off the cuff and improvising, creating chances and scoring goals and we’ve done that brilliantly at times this season.

“You saw that last season as well, the desire to win is huge here. We love that buzz of winning and not wanting to lose is the most important thing.

“You saw that in the way we got the draw against Hibs last time out – we could even have nicked the win in the end.

“Just not losing is our mentality right now. We’ve had that throughout the season. It has put us in good stead and hopefully we can continue that.”

And Roberts has insisted that Celtic’s mood fits their winning ways.

“Everyone is in a good mood right now – we’re winning games and playing good football and that’s what we like,” he said.

“Obviously, we know that we need to win games but we still go out there and have fun and everyone has a smile on their face.

“The main thing for us is to enjoy it – there are always going to be bad times in football so we need to be able to enjoy this.”

Celtic have been able to eek out games with late goals, something that Roberts puts down to the Parkhead side’s superior fitness.

“The coaches here work us hard on our fitness off the ball,” he said. “We keep going to the end.

“We made a few substitutions, which we can do. We have quality off the bench. It’s about the big squad we have.

“In the last 20 minutes, we can turn the game on its head and turn up the tempo.

“When teams get tired, we can really go at them and try to get the win.”
