Holders Real Madrid will begin the defence of their Champions League title in a tough group with Borussia Dortmund and Tottenham Hotspur after Thursday's draw, which saw French clubs Monaco and PSG land in relatively comfortable groups.
Zinedine Zidane's Madrid are chasing a third successive European title and fourth in five seasons after demolishing Italian champions Juventus 4-1 in Cardiff in June.
The record 12-time European champions also take on APOEL of Cyprus in a testing Group H that will see Gareth Bale face Spurs for the first time since leaving for Real in a then world record deal in 2013.
"We are the holders so there is always an extra motivation for the teams you face. It won't be easy at all, we'll need to play well and find our best form," said Real spokesman and former striker Emilio Butragueno.
"We've played a lot of times against Borussia Dortmund recently and know how good they are. Tottenham have shown in the Premier League they are a very strong team."
Tottenham forward Harry Kane said he was excited to line up against the defending champions.
"You want to test yourself against the best and Real Madrid are the best at the moment," said Kane.
Elsewhere, Barcelona were drawn against Juventus, whom they beat 3-1 in the 2015 final.
They will also come up against Greek champions Olympiakos and Sporting Lisbon in a competitive Group D.
"It is a high level group with four historic teams. We will be fighting against a well known rival in Juventus and the games against them will condition our chances in the group," said Barca general manager Pep Segura.
Juventus director general Beppe Marotta said Barca were weaker following the record-breaking sale of Neymar.
"Missing a player like Neymar weighs heavily. We'll have to see how they intend to replace him. But Barcelona remain a top quality side with great individual players," Marotta told Italia 1.
Ancelotti back in Paris
Bayern Munich coach Carlo Ancelotti will return to Paris in a Group B that also features Celtic and Anderlecht.
"It's an exciting group with some great teams and Paris at the top," said the Italian.
"It's a nice story for me to meet my former club again. As everybody knows, Celtic get incredible support from their fans. And Anderlecht can not be underestimated as Belgian champions."
PSG coach Unai Emery, looking to mastermind a much deeper run after last year's spectacular collapse against Barca, expects his side to join Bayern in the last 16.
"Bayern Munich are a very strong side. We will be the two favourites," said Emery.
Chelsea, one of a record five English teams to qualify for the group phase, will meet Atletico Madrid in Group C as well as Roma and Qarabag, the first side from Azerbaijan to reach this stage of the competition.
Jose Mourinho will visit his native Portugal with Manchester United after they were placed in Group A with Benfica, CSKA Moscow and Basel.
Pep Guardiola's Manchester City are in Group F alongside Shakhtar Donetsk, Napoli and Feyenoord while Liverpool will play Spartak Moscow, Sevilla and Maribor in Group E.
"We want to be a football club where we are always there in the quarter-finals, semi-finals and getting to finals," said City director of football Txiki Begiristain.
"We have refreshed the team and we are hoping that we can remember what we did two years ago when we got to the semi-finals and why not even more?"
Liverpool coach Jurgen Klopp was pleased to have avoided Europe's heavyweights.
"There are groups with Barcelona, Bayern, Juventus and Real Madrid, and not to get them is of course more good than bad," said Klopp.
French champions Monaco, who reached last season's semi-finals, face Porto, Besiktas and debutants RB Leipzig in Group G.
The opening round of matches will be played September 12-13.
