The Premiership leaders are four points away from clinching the title after Sunday's 1-1 draw with Rangers.

But they have a 19-goal advantage as well as a six-point lead over Rangers and victory over Hearts on Saturday would effectively put the title beyond the realistic reach of their city rivals.

If Rangers then beat Dundee United on Sunday, Celtic would have the chance to officially seal the title at Tannadice on Wednesday and then enjoy a trophy celebration at home to Motherwell on May 14.

Postecoglou's side have scored 81 league goals so far and he wants them to continue their free-scoring form in the final three matches of the season.

"Obviously, after last weekend's game, I think for everyone there was quite a bit of emotion and physical exertion on the day so we gave the boys a couple of days off to recover and refresh them a little bit," the former Socceroos boss told Celtic TV.

"We are back in training and looking forward to it. It's been a challenging year but we are in the final straight now. We know as a group we have 10 days together and we want to make the most of it.

"It's kind of a tricky one because you don't want to fall over the line and just get it over and done with. It's important you actually enjoy this bit.

"We want to finish strong and make sure we play our best football at the most important part of the year and we are going to have to be good on Saturday to do that."

It was confirmed this week that Scotland's title winners would go straight into the Champions League group stage, so Postecoglou could be dining at European football's top table next season.

"I was well aware at the beginning of the year that that was the likelihood so we knew it was an important title to win because of all the benefits of guaranteed Champions League football," Postecoglou said.

"That's the level we all want to be at, that's the level we want this football club to be.

"Of course, that's a massive incentive but first of all it's to bring some joy and success to our supporters, particularly after last year when we didn't have any success."
