As the world's most successful football player, Lionel Messi has left Paris Saint-Germain (PSG) to join his long-time rival Barcelona. The Argentine star announced on Monday that he would be leaving PSG after six seasons with the club, where he won two league titles and one Champions League.

The departure of Messi from PSG has been widely anticipated, as the French giants have struggled to compete with other top clubs in Europe in recent years. With the arrival of new manager Mauricio Pochettino and the signing of Kylian Mbappe, PSG were hoping to turn things around and challenge for the title again this season.

However, Messi's decision to leave PSG will likely have a significant impact on the team's future plans. While PSG may look to bring in a replacement for Messi, it is unclear who they will target or how much they will have to pay to acquire him.

For now, the focus will shift to Messi's next move, which could be a big one. He has expressed interest in returning to Spain, where he spent most of his career before moving to France, and there are reports that he could make a return to Barcelona. However, there are also rumors that he could end up at another Spanish club, such as Real Madrid or Atletico Madrid.

Whatever his next move may be, it is clear that Messi's legacy at PSG will continue to be felt for many years to come. As one of the greatest football players of all time, he has left a lasting impression on the sport and will be remembered for years to come.
