I think, it will be difficult for PSG to win this season trophy because their starting in this UEFA champions competition, showed that they will not go far in this season if their coach continue benching some of the players that know how to attract early goals on the first half. If PSG coach can work on their midfield before their next match, I believe there will be massive change, because their strikers are lacking help from their midfielders. I don't think Ajax can defeat Manchester city in this season, because many things has changed in Manchester city in this season that will make them unbeatable through out this tournament.
