Kylian Mbappe is capable of marking an era at Real Madrid and could be somewhat unfulfilled at Paris Saint-Germain, according to Unai Emery.
Mbappe, 21, has been heavily linked with a move to Madrid with his contract at PSG expiring in 2022.
Emery coached the France international for a season at PSG in 2017-18, when they won Ligue 1, the Coupe de France and Coupe de la Ligue together.
The Spaniard believes Mbappe has the talent to create a spectacular period at Madrid, if he decided to make the move.
