Van Bronckhorst only focusing on Rangers during hectic December
The Ibrox side kept a four point lead at the top of the table
Rangers boss Giovanni van Bronckhorst insists he is not interested in what is happening across the city following their 2-0 win over St Johnstone.
The Ibrox side almost stretched their Premiership lead to six points, but Anthony Ralston scored an injury time winner for Celtic in Dingwall.
A cheer went up inside the stadium when news came through of Ross County's equaliser earlier in the second-half.
Asked if he was taking any notice of Ange Postecoglou's side, Van Bronckhorst told Sky Sports: "As a player I was always concentrating on my team.
"As a coach you only have influence on the games we play.
"We just go into every game to win it and get the three points we need.
"That's all I thought about tonight."
St Johnstone boss Callum Davidson confirmed Chris Kane will miss their next two matches after being forced to self-isolate.
A positive coronavirus case in his household means he'll be unavailable for 10 days.
Davidson expects it's just the start of similar issues for all clubs.
He said: "It's not just going to be us at St Johnstone, it's going to be everybody.
"It's a real tough one when you lose a player like that.
"We don't want to spread the virus but when the rules are just as clear-cut like that, it's not just going to be ourselves".
