PSG have won the League and UCL this season. They are in perfect form in Ligue 1, with only 2 defeats and a huge point gap from 2nd place Marseille. It seems that they will not make many big transfers. It seems that Enrique will only add a few players as a strategy for the tight competition. But it all depends on the condition of the players who leave. I think many players will get new offers from other European clubs because of PSG's good performance. One of them is striker Goncalo Ramos who Man United want.

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.
