Hard for me to predict the matches of Inter vs Ajax and PSG vs Man United. These 2 games seems 50:50 for me, the other matches are mostly to be easy win for the teams in bold. PSG vs United is the most interesting one as we will see the duel of Messi vs Ronaldo. I cant remember when was the last duel between these 2 players but I'm sure it will be a great match as the condition of both team is not in their best, that's why it is a 50:50 for me.
