PSG biggest dream will be to win at least 1 champions league title, they've won the league title many times so I do agree about the main focus on UCL but even with the main focus, they still haven't even proof any sign of qualification for it ... When there was even enough resources they couldn't still make it happen, imagine having Messi, Neymar,Mbappe,Ramos, Hkimi, marquinhos, Veratti ,Kimpembe.... and still couldn't make use of the resource to archive a sole purpose of bringing such starts together
. Though I don't know the squad depth when Enrique started but as at the moment the squad is not a squad that can win Champions league
That will not only be their dream but every other persons dream and if you want to win the champions league it won't stop as a dream their somthing that you have to work towards it, and most title that they have won is not more than league 1 and mostly other France leagues and win the champions league is somthing they can do if they are serious about how they want to win it exactly, if they have to get new players it won't be a bad idea but if you look at it, psg have spent a lot of money on getting super players and still nothing yet, for them.
When you say sign of qualification it's high they have not don any serious advancement in trying to win but I just hope some day they will be able to make their dream come through by winning the champions league. They actually had the time and resources then but they were still unable to win it and that is why it is a dream, and that is one of the reasons mbappe wanted to leave to be able to win the champions league, and things are now different, the condition of psg in the champions league is worse.
