LIVE: Man Utd, Liverpool, Man City and Tottenham's Champions League groups revealed
Manchester United will have a Cristiano Ronaldo reunion in this season's Champions League after being drawn in the same group as the Portugal star's new club Juventus.
Premier League champions Manchester City will be delighted with their draw, after being grouped with Shakhtar Donetsk, Lyon and Hoffenheim in Group F.
