Derek McInnes is confident Hearts can "tear up the script" one more time this season to claim the Scottish Premiership title at Celtic Park on Saturday.

Hearts know they will be champions for the first time since 1959-60 if they avoid defeat against Celtic, who will overtake them and retain their title if they are victorious.

If they get over the line, Hearts will become the first non-Old Firm side to be crowned champions of Scotland since Alex Ferguson's Aberdeen in 1984-85, ending a run of 40 successive titles won by either Celtic or Rangers in the process.

And if they do it by collecting all three points, they will become the first team in Scottish football history to win six games against the Old Firm clubs in a single league season.

And if the Opta supercomputer's predictions are to be believed, it could hardly be any closer – Celtic win the title in 50.4% of simulations, with 49.6% going Hearts' way.

But McInnes believes his team are ready to cause a surprise, saying: "It's a perfect ending to a season for the league, for Scottish football, for drama and excitement. It's pure box office.

"I felt for a while it would go the full way, and we've been preparing for that. We knew we'd have to get good wins, and obviously, Celtic have shown improvements. 

"Fair play to them and to our boys for making this the situation. It's important now that we have that one big performance in us to try and get over the line."

Asked what he expected the atmosphere to be like back in Edinburgh, with only 800 Hearts fans making the trip to Glasgow, he added: "It'll be bedlam, it'll be an unbelievable atmosphere.

"There might be people out there who think everything's back on script – if Celtic win their home game, they win the league.

"But we've ripped the script up so often this season, and we've got one more in us, I think, and it's up to us to try and make that happen."
