Group H: Juventus and Manchester United
Juventus have impressed in the Champions League in recent seasons without actually winning the trophy. Who better to help the Old Lady get over the line than the man who has constantly tormented them and halted their progress? Cristiano Ronaldo's signing has been seen as one which could see Juventus go all the way with the man boasting five UEFA Champions League titles and holding the record for the most goals UCL history with 120.
It would be hard to imagine a Jose Mourinho managed side getting eliminated in the group stage and Manchester United have enough quality to qualify. Despite their early-season concerns, United are expected to have clicked into gear once the Champions League starts and will be a force to be reckoned with in the tournament.
Valencia are a really good side but their inconsistency and the fact that they haven't experienced the UCL knockout rounds since the 2012/2013 season will ultimately hold them back.
Fresh from their first Swiss Super League title in 32 years, Young Boys will make their debut in the Champions League group stage. Any points gained will be an achievement and qualification is highly unlikely.
