The UCL this season is tough, I must admit. I certainly cannot deny the fact that the teams almost have equal chances of winning it. However, I would still go with the defending champions, Real Madrid.
It's not so hard if the club was getting in the other group where almost all of participants are coming from serie a. All of hard opponents were playing in the same group. You can imagine how hard the group that has been filled by chelsea, real madrid, bayern and manchester city.
This is far hardest compared with the group that has been fulfilled by serie a clubs. I hope that benfica will able to destroy serie a club. Benfica is very strong right now. It can't be underrated even though was napoli in that group/
Benfica will able to win easily against napoli.
Though, odds may not be in their favour, I just have a hunch that they would come out victorious. They may not be very consistent in their League games but they are very experienced when it comes to Champions League football. I don't see any team stopping them this time.
Chelsea has won UCL two times, and madrid 14 times. Bayern has also ever won UCL too but city has none. It has proven how strong the teams that were playing in these groups. Real madrid is the most favorite club right now to win UCL.
Real madrid already won UCL last year and it may repeat the same story again. Madrid is very capable to win against any clubs in its group. The best team in the world.
