Confident John Hartson has declared Celtic are on their brink of taking "their" title back from Rangers after derby day.
It was a crucial showdown at Ibrox with victory handing Ange Postecoglou 's a six-point lead at the top of the table.
It leaves Giovanni van Bronckhorst with a mountain to climb to keep the trophy in the blue side of Glasgow.
Celtic hero Hartson held back on completely writing off Rangers but reckons the Premiership trophy is nearly back in the Celtic Park trophy cabinet.
He told the Go Radio Football Show: "It's a huge time to score, just before half time. What Rangers needed to do today was not lose.
"Even if they got back to 2-2 there they are very much in the race. They are now six points behind and 16 goals behind, effectively seven points.
"It's a long way back now. Celtic will need to have a monumental lapse in terms of games and points and everything else. Celtic are firmly favourites to get their title back.
"There are six games to go and lots of other games, the Scottish Cup, there is still so much to play for."
