Chelsea striker Olivier Giroud admits the talent of Kylian Mbappe is "breathtaking".

The PSG striker won the World Cup playing alongside Giroud for France in the summer.

The Blues centre-forward said: "He is breathtaking with his talent and maturity.

"One wonders where he will stop. At the same age, I have never met a boy so strong. It's unheard of.

"Perhaps not since Thierry Henry have we seen someone like this."
