CALLUM McGregor admitted Celtic failed to show a reaction when they went a man down against Livingston but said the team would keep up the hard work and hit the reset button upon their return to action.

Celtic's unbeaten domestic run this season came to an end in Sunday's 2-0 loss away to Livingston.

Neil Lennon’s side travelled to Almondvale three days after defeating Cluj 2-0 in the Europe League and looking to continue their strong form in the Premiership. However, the exertions from the midweek fixture were compounded when Celtic were reduced to 10 men after Ryan Christie was sent off.

Speaking after the game, McGregor said Celtic's performance was disappointing and added the team should have responded better following the dismissal

“We’re massively disappointed,” said the Celtic midfielder. “We knew it was going to be difficult with the pitch and their style of play, they get in about you. We didn’t perform and were left wanting a bit in that department in terms of second balls and really competing against their style.

“There’s no blame attached to Ryan at all. He’s been amazing for us this season and dug us out of holes plenty of times. It’s a bad tackle and you get that in football when you mis-time things. We needed to show a reaction when we went down to 10 men, and at times in the past we’ve done that and come away with three points. But we never reacted as well as we should have.

“We spoke at half-time about trying to dictate the play in terms of how we want to play the game. But they scored early and that got their tails up and gave them more oxygen in the game and made it more difficult for us to get back into it.”

The upcoming international fixtures mean Celtic will have to wait almost two weeks before they can put right the wrong sustained by the loss, and McGregor insisted the champions are determined to do exactly that.

“It’s disappointing to go into the international break knowing you haven’t finished as well as you’d wanted,” said McGregor. “You have to wait two weeks for the game to come around again before you can try and put things right. I’m sure everyone will go away, keep working hard, hopefully come back fit and we’ll press that reset button and go again.”
