Celtic have been drawn with Barcelona, Manchester City and Borussia Monchengladbach in Group C of the Champions League.
Brendan Rodgers' side booked their place by beating Haopel Be'er Sheva 5-4 on aggregate in the play-offs and can now look forward to a series of glamour ties.
Celtic met Barca in the International Champions Cup in Dublin last month and famously beat them 2-1 at Parkhead in November 2012 courtesy of a Tony Watt winner.
