All roads lead to Paradise as Celtic entertain Rangers in the fourth Glasgow derby of the season.

A win for Ange Postecoglou's men would all but see green and white ribbons draped around the Scottish Premiership trophy for the second year in a row as the Aussie's side would surge 12 points clear of their city rivals.

The 57-year-old still has fitness doubts over left-back Greg Taylor and midfielder Reo Hatate but Aaron Mooy looks to have won his own battle for selection.

Rangers supporters will be locked out of this crucial powderkeg clash at Parkhead after both sides opted not to take up their ticket allocation for the final two derby fixtures of the season.

The Hoops will be aiming to crank up the pressure once again on Michael Beale's Light Blues whose title hopes will be on the line in this crunch encounter.

The visitors will also be mindful that Hoops have blown their rivals away 3-0 last February and 4-0 back in August on their last two visits to Glasgow's east end with the Rangers players visibly cracking under the atmosphere inside the ground.

Meanwhile, the eyes of the football world will also be on referee Kevin Clancy and the VAR officials in light of former Celtic striker Andy Walker being forced to apologise by his employer Sky Sports for his controversial VAR claims.

The pundit and co-commentator admitted on a podcast that earlier this season he had overheard a VAR assistant telling the referee "the easiest way out" of a call was "if it was offside". Walker refused to name the officials or clubs involved in the incident.

Amazingly Walker chose to divulge information that he and his Sky Sports colleagues could hear secret discussions between the VAR officials at Clydesdale House and the referee during the game in question.

However, Walker's comments had angered the members of the Scottish Football Referees Association which has led to fears that Sky's feed of the VAR system could be eradicated and withdrawn in the future Walker has since "admitted his regret" over his remarks.
