The quarterfinals are a little difficult to predict because looking at the current situation we clearly know that by reflecting on the previous phase then for 4 matches in the quarterfinals will feel a little inconvenient for 1x2. I still have faith in Madrid and Chelsea at 1x2 but for Bayern against PSG and Fluminense against Al Hilal it's a bit tricky for 1x2 so I would prefer to be back on the over in these matches.
I have selected the clubs that I will bet on in the quarterfinals and Real Madrid is not an exemption but I wouldn't bet on Chelsea because I can't really rely and have full confidence in them. I will bet on Al Hilal to win Fluminense despite the fact that they are the best club in Brazil. PSG to win Bayern is likely to happen because PSG is in their best form currently.
