Celtic have been handed a relatively favourable draw after being demoted down to the Europa League group stages.
The Scottish giants missed out on a place in the Champions League after losing to Maribor earlier this week, but manager Ronny Deila will be pleased with his side's group for the Europa League.
The Glasgow-based side will play Austria's Red Bull Salzburg, Croatian outfit Dinamo Zagreb and Romanian side FC Astra.
The first round of group fixtures take place on September 18.
