Other teams in that pot include AC Milan, Marseille, who were beaten by Atletico Madrid in last season’s final, Sporting Lisbon and Fenerbahce.
Rangers, after overcoming Ufa in their play-off, are in pot four, which also features Slavia Prague and Rosenborg.
Pot three includes Real Betis, Red Bull Leipzig, Eintracht Frankfurt, Bordeaux and Rennes.
While Celtic and Rangers secured their places in the draw on Thursday night, Burnley’s hopes of making the group stage ended as a 1-1 draw against Olympiakos at Turf Moor in the second leg of their play-off saw them lose 4-2 on aggregate.
With the Clarets knowing a 2-0 win on Thursday would send them through, Sam Vokes failed to convert two good chances and hit the post, Ashley Barnes shot just wide and Dwight McNeil was denied by a good save before Olympiakos netted through Daniel Podence in the 83rd minute. Substitute Matej Vydra replied three minutes later.
Burnley boss Dyche said: “It was an excellent performance from start to finish.
“We created so many opportunities to win the game and didn’t quite win it of course. Just to win it would have been at least what we deserved, and probably to go through, if you do take your chances – but we didn’t take our chances, and that has to be the only blot on the copy book really.
“(I was) very pleased and very proud of the players, without a doubt.”
REACTION | “Very very proud of the way the players have gone about it…”
