I start to say that PSG looks really stronger than last year. They kept all their players and also bought even better players like Cavani, Marquinhos, Digne. They also signed some young from their academy who can be a good help when needed.
They (players) looks to be really more concentrate on the project too, and I think Blanc is a nice choise as a coach.
They have no reason to not win the championship, except if they are too arrogant. But the most important for them will be to try to fight to win the UCL, wich his the project of the chairman.
