PSG will remain the best team in League One because I don't think there is any other team in the tournament that comes close to them in terms of performance since they have been dominating the League One for a long even when Mbappe and other star players are injured.
Since the team has money, they should give Luis Enrique some money to shop for more players that can help the team achieve their main aim which winning the Champions League; if they don't add some quality players, they will do well in the League one, but can fail when it comes to Champions League.
They are very capable of digging very deep into their pockets, because they have a lot of money at the moment. But the question is how effective would it be if they did it? Because as said, if only to dominate Ligue 1, what they have now, in my opinion, is enough to make them achieve.
Developing young players to become very reliable players will provide benefits for the club, for example, when PSG is able to develop reliable young players, the club will definitely get the title they want because these young players already know what to do when joining PSG and this is an alternative which is simple and more promising than bringing in professional players at high prices but not getting what you want.
PSG must learn from previous problems and do not need to make the same mistakes.
It's time for PSG to rise up with young, reliable players.
