Mbappe's mother names the biggest club in the world after her son joins Real Madrid.

Fayza Lamari, Kylian Mbappe's mother, claims Real Madrid is the world's biggest club.

The French captain was officially revealed by the Spanish club on Tuesday, after leaving Paris Saint-Germain as a free agent.

According to Fayza, the contrast between the two clubs is obvious.

"Real Madrid is the biggest club in the world," he remarked.

"On Tuesday, I noticed a difference, for example, with PSG.

"The Parc des Princes is magnificent. But when you get to Real Madrid, you feel the weight of the institution."

Fayza also serves as Mbappe's agent.
