Tempers are boiling over in the Scottish Premiership after a controversial 99th-minute penalty decision handed Celtic a dramatic 3-2 win over Motherwell—and left Hearts head coach Derek McInnes fuming at what he called a "disgusting" call.

With Hearts cruising to a 3-0 victory against Falkirk, it looked like the league leaders were on the verge of securing the title in style. All they needed was for Celtic to drop points at Motherwell, and the trophy would be theirs for the first time since 1960. But football had other plans.

Deep into stoppage time, VAR official Andrew Dallas summoned referee John Beaton to the pitchside monitor after a high ball challenge between Motherwell's Sam Nicholson and a Celtic player. Replays appeared to show the ball striking Nicholson's head—not his raised hand—but Beaton saw it differently and pointed to the spot. Kelechi Iheanacho stepped up and coolly converted, snatching a 3-2 win for Celtic and keeping the title race alive for a final-day showdown at Celtic Park on Saturday.

The decision sparked outrage across the football world. Former England striker Gary Lineker called it "maybe the worst VAR decision I've seen... extraordinary given the significance." McInnes didn't hold back either, telling Sky Sports: "When you heard Celtic had a 96th-minute penalty going to VAR, you just assume they get it. It's disgusting. We're up against it, we're up against everybody. It's so poor and it looks as though they've been given it. They have been very fortunate."

Had Celtic dropped points, Hearts could have afforded to lose by two goals at Celtic Park and still be crowned champions. Now, they must avoid defeat to become the first team outside Celtic or Rangers to win the Scottish top flight in four decades—a historic achievement that's now on the line.

"It's going to the last game. We're delighted to be part of it," McInnes said. "To do it, we're going to have to go and get a positive result. I'm looking forward to it already."

With everything on the line, Saturday's clash at Celtic Park promises to be one for the ages. Will Hearts hold their nerve and make history, or will Celtic's controversial lifeline spark a dramatic title turnaround? One thing's for sure: you won't want to miss a minute of the action.
