The summer transfer window is upon us, and Paris Saint-Germain (PSG) is looking to make some key signings in order to optimize their squad for the upcoming season. As the club prepares for the transfer market, they will have to weigh up the benefits of retaining their existing players against the potential risks of selling them.

One of PSG's most important players is Lionel Messi, who has been at the club since he was just 14 years old. The Argentine forward has scored over 400 goals for PSG, and his presence on the pitch is crucial for the team's success. However, as the club looks to strengthen its squad, it may be difficult to convince Messi to stay at PSG beyond the end of his contract in June 2022.

Another player that PSG could consider selling is Kylian Mbappe, who has been linked with a move to Real Madrid. The French winger has been instrumental in PSG's recent success, scoring 65 goals and assisting 27 more in all competitions this season. While Mbappe's value is high, there may be concerns about the financial impact of losing him, especially given the club's budget constraints.

Despite these challenges, PSG is still likely to make some key signings during the summer transfer window. The club is believed to be interested in signing a new striker, as well as defensive reinforcements. It remains to be seen how PSG will approach the transfer market, but one thing is clear - they will need to make some tough decisions if they want to maximize their chances of success next season.
