Manchester City, Liverpool, Chelsea, Tottenham Hotspur, Celtic and Rangers are in the draw for the Champions League Group stage later today.
It's the first time since the 2007-08 season that both Old Firm clubs have made the UCL group stages.
32 teams will be split into four groups of eight, with the matches to take place between September and November.
No clubs from the same country can be drawn in the same group.
The draw starts in Istanbul at 5pm.
