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.
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.
