Paris Saint-Germain announced the signing of Dro from Barcelona on Monday.
The 18-year-old winger has signed a deal with the French champions through 2030.
A product of the vaunted La Masia academy, Dro made his first team debut in Sept. and made four league appearances.
“I’m very happy and very proud to be joining Paris Saint-Germain,” the Nigrán, Spain native said. “This is a moment of huge pride for me and for my family. PSG is a massive club that I’ve followed since I was a child and where some great legends have made history. Right now, I’m hugely excited and motivated to play and to give everything for this shirt.”
Dro has been given the No. 27 shirt.
Internationally, Dro has played for Spain at a variety of youth levels, most recently with the Under-18 side.
PSG currently sits atop the Ligue 1 table on 45 points, two clear of Lens through 19 matches. The team returns to action on Wednesday when they welcome Newcastle in Champions League play.
