Although Manchester City, Real Madrid are opponents of each other, we definitely consider these two teams as strong rivals in the Champions League. Along with Manchester City and Real Madrid, Bayern Munich are quite strong in the Champions League tournament this season and we can list Arsenal as the favorites for the Champions League competition. Arsenal have been consistent since the start of the season but they need to be a bit more consistent as the upcoming matches are definitely tough and if Real Madrid can't perform in line with Manchester City and Bayern Munich in the upcoming matches then Bayern Munich won't do well. If Manchester City and Real Madrid qualify for the semi-finals, I would like to see Arsenal and Bayern Munich qualify for the semi-finals. Because if all the strong teams lose in the quarter final then the final match will not be good at all.
We can't currently tag any team as hot favourite for the title with eight top teams are already in quarterfinals and things can go either way which are surely not easy to predict even after exit of Inter Milan now we have interesting situation Real Madrid is going to face Manchester City which is also interesting, and again we will have Bayern Munich or Arsenal for the next round with these things are going to be entertaining because in other group we have Atlético Madrid, PSG and Barcelona which are currently not strong enough as we have rest others.
Just because of this all currently predicting about winner is not easy, any team can create surprise on match day performance which is part of the Champions League history it's never been as we have all on papers.
