"This year, Christmas comes on December 23."
With this message and a 36-second video showing a figure wearing a hooded jacket in various locations around Lyon, the French outfit announced the signing of Endrick.
The Brazilian had reached an agreement weeks ago to spend the next six months with Lyon, after it became clear that Xabi Alonso did not have him in his plans at Real Madrid, who were still negotiating the final details of the deal just hours before the announcement.
Lyon wanted to include a purchase option, but Madrid refused, as they still believe the player can be important and have a future at the Bernabau.
Endrick will join his new team on December 29th, with the French club paying around one million euros for his loan.
