Well City got what they wanted. New cities to explore in Europe. Turin, Seville and Monchengladbach. However, Juventus will be beatable I think. Juventus have lost their players like Vidal, Tevez, Pirlo and they are about to lose Pogba. They will finish similarly how they did 2 years back, when they were 3rd. Sevilla, on the other hand, are a tough opponent and I expect them to top the group with City second. City ended with the hardest Pot 3 team. Monchengladbach should be easy 6 points in the bag.
Man Utd got a decent group. PSV the only weak link. I expect Utd to top the group with CSKA in second. Actually, this group is a repeat of the group of 2009-10 group stage but instead of PSV, it was Besiktas. Utd and CSKA were the teams that progressed. CSKA also nearly won at OT, 3-1 but ended up with 3-3. Wolfsburg will be easy, they're overrated IMO, a team lost 6-1 on agg to Everton lol. Plus, without KDB, they'd be worse. But it would be scenes if CSKA get City in the knockouts.
Group of Death IMO is the Madrid, PSG and Shakhtar. But still, PSG and Madrid will progress. Shakhtar sold their best player.
