PSG star Kylian Mbappe is backing Christopher Nkunku for success at Chelsea.

Nkunku enjoyed a first training session with the Blues yesterday.

The former RB Leipzig striker signed for Chelsea in midseason before joining the Londoners last month.

Mbappe is close to his France teammate and was aware of Nkunku's first training session.

He posted to social media: "I'm going to get the popcorn."
