Kylian Mbappe completes 'dream' move from Monaco to PSG on one-year loan deal
France international striker Kylian Mbappe has joined Paris Saint-Germain from Monaco on a season-long loan, the two clubs announced on Thursday just hours before the transfer deadline.
"The loan agreement also includes an option to buy which, when exercised, will bind the player to Paris Saint-Germain until June 30, 2022," PSG said on the club's website.
According to media reports, the overall transfer fee could rise to €180 million (Dh783.6m) including add-ons, which would make Mbappe, 18, the second most expensive player in history behind his new teammate Neymar.
"It is with great joy and pride that I join Paris Saint-Germain," Mbappe told the PSGT website. "For any young person from the Paris region, it is often a dream to wear the red and blue jersey and experience the unique atmosphere of the Parc des Princes.
"I really wanted to be a part of the club’s project, which is one of the most ambitious in Europe. Alongside my new teammates, I intend to continue my progression while helping the team achieve the very big objectives it has set itself."
