Ange Postecoglou takes his league leading Celtic players across the city to Ibrox, home of the reigning champions and arch-rivals Rangers, carrying a three point lead with six more matchdays to come.
The outcome then will either leave the teams level, the margin intact at three points or extended to six points – which means much rests on the outcome of the 90 minutes on the city’s southside this lunchtime.
Postecoglou had a full strength side to choose from with only James Forrest unavailable for selection and the manager has named his team seeking a repeat of the 3-0 success in the last encounter, rather than another 1-0 defeat they endured on their last visit to Edmiston Drive.
Here are the players the Celtic manager has placed his faith in for what promises to be a seismic match in the Scottish Premiership title landscape.
