Analysis - who got the best draw?
Simon Gleave, head of sports analysis at data company Gracenote:
Amongst the English clubs, it was Liverpool whose chance of progress to the Champions League knockout phase suffered the most.
Prior to the draw, we gave them a 69% chance of reaching the last 16 - but after drawing Paris St-Germain, Napoli and Red Star this has dropped to 54%.
PSG have an 80% chance of progress, Napoli 60%.
Before Thursday's draw, we gave Manchester United a 73% chance of progress, but after drawing Juventus, Valencia and Young Boys, that decreased to 65%. Juventus are favourites to get out of Group H (95%), Valencia have a 30% chance and Young Boys 10%.
Tottenham Hotspur's chance of reaching the knockout phase declined slightly from 76% to 74% after ending up in a group with Barcelona, PSV and Inter.
Manchester City's chance of progress to the last 16 remained at 91% after they were drawn with Shakhtar Donetsk, Olympique Lyon and Hoffenheim.
Real Madrid clean up in Uefa awards
Real Madrid, who beat Liverpool 3-1 in last year's final, cleaned up in the Uefa awards, with their players winning in all the categories.
Keylor Navas won the goalkeeper of the season award, Sergio Ramos was voted the best defender, while Cristiano Ronaldo claimed the forward of the season award.
Croatia international midfielder Luka Modric - a Champions League winner with his club and World Cup finalist with his country - won both the midfielder of the year and overall best player awards.
Meanwhile, former Manchester United and England midfielder David Beckham was awarded the Uefa President's award.
"From winning the Champions League with Real Madrid, achieving a historic result with Croatia, now this, it is amazing," said Modric. "They are great feelings and I am happy and proud of everything that I have achieved.
"This year I can say is the best year of my career, collectively and individually. Finally I achieved something I dreamed since I started playing for the national team. We reached the final of the World Cup and even without winning it was historic."
