The Paris Saint-Germain (PSG) have been one of the most successful teams in European football in recent years, and they continue to be one of the favorites to win the UEFA Champions League this season. However, with the transfer window now open, there is talk that PSG may need to sell some players in order to make room for new signings.

According to reports, PSG are looking to sell five players in the summer transfer window, including key players such as Kylian Mbappe, Neymar Jr., and Lionel Messi. These players have all been linked with moves away from the club in recent months, but it remains to be seen whether any of them will actually leave.

If PSG do decide to sell these players, it could have a significant impact on their squad composition and ability to compete at the highest level. The loss of key players such as Mbappe, who has scored 71 goals in 94 appearances for PSG, would certainly be a blow to the team's attacking capabilities.

However, if PSG were able to bring in replacements, they could still be considered one of the top teams in Europe. In fact, there are already rumors suggesting that PSG are interested in signing Manchester United striker Romelu Lukaku and Chelsea midfielder Jorginho, both of whom are highly regarded by fans and critics alike.

Overall, the sale of key players such as Mbappe, Neymar Jr., and Lionel Messi would undoubtedly have an impact on PSG's squad composition and ability to compete at the highest level. But if PSG can find replacements that are capable of filling the void left by these players, they could still be considered one of the top teams in Europe.
