“When you heard Celtic had a 96th-minute penalty going to VAR, you just assume they get it,” the incandescent Hearts head coach told Sky Sports.
“It’s disgusting. We’re up against it, we’re up against everybody. I don’t think it’s a penalty. It’s so poor and it looks as though [Celtic] have been given it. They have been very fortunate.”
Had Celtic dropped points, Hearts could have afforded to lose by two goals at Celtic Park on Saturday and still be crowned champions for the first time since 1960.
Now, though, they must avoid defeat if they are to become the first side outside Celtic or Rangers to win the Scottish top flight in four decades.
“It’s going to the last game. We’re delighted to be part of it,” McInnes added.
“To do it, we’re going to have to go and get a positive result. I’m looking forward to it already, there’ll be no feeling sorry for ourselves. What a game it’s going to be.”
