I bet on PSG in this match because I just want and am thinking about PSG reaching the final. PSG reached the final after winning by a large margin against Real Madrid, PSG beat Real Madrid by a huge margin. PSG is performing very well this season and they are ready to win against any strong team.
Chelsea players are still in a sleepy state, they are performing the same way they are currently, there is no sign of any attacking performance in them. So I will bet on PSG and not Chelsea and the chances of winning will be very close.
