The Scottish side lead Group D on eight points – the same number as Benfica but with a better goal difference – and a win here would guarantee their spot in the last 32.
Meanwhile, Liege are bottom of the group – level on three points with Lech Poznan but with a worse goal difference. Anything other than a victory at Ibrox will see the Belgian outfit crash out of the tournament, but – given their 2-0 home defeat by Rangers in their competition opener – they seem to be facing a tough task.
