They will not make any player transfers if it is to win Ligue 1. PSG really dominates in Ligue 1 and I think they will still be champions again this season. But I think PSG must still make some transfers such as to regenerate players or get young talents who have not been glanced at by other clubs. And with their impressive performance I think there is a possibility that some PSG players will leave the club because they get offers from other clubs. I think these are some situations that show that PSG cannot just rely on the same squad as this season for the future of the club. They will compete in the FIFA Club World Cup this year. And now they are one of the favorites to win the UCL. This is a good momentum for PSG to maintain the depth and quality of their squad.
Previously, PSG was rumored to be interested in the young talent of the Argentine National Team, Franco Mastantuono. But it seems that PSG's interest is hampered by competition from Madrid.
I am sure PSG also has several names of players that they will bring in. The competition in Ligue 1 may not be too tight for PSG. But for the Champions League, with all teams definitely improving their teams, PSG cannot just be satisfied with the current team.
I think that the talent that Mastantuono has is seen by Paris Saint-Germain at Real Madrid. It is seen that two teams are competing for him. It is important who will win this race because Mastantuono is an important star candidate for the future. Real Madrid has stronger connections in South America and Real Madrid is more respected there. Therefore, the young Argentinian star candidate may choose Real Madrid.
