As the French players lined up yesterday, the Tunisian team cast anxious glances towards one man - this time, sitting on the bench.

To have any chance of winning the game, opposing teams need to control Kylian Mbappe. Thought to be the greatest player on the planet, he can destroy any defence when he is on form.

In France's first match, he rose above the Australian defence to score with a glancing header. In their second game, he scored both French goals in a 2-1 victory over Denmark.

This time, Mbappe's appearance in the second half was not enough to save France's match. But despite the 1-0 loss to Tunisia, Mbappe has undoubtedly led his team to the knock-out stages.

According to Alan ShearerAn English football pundit who scored 260 goals in the Premier League., Mbappe can score any kind of goal. Close dribbling, long shots, curling shots, dinks, flicks, side-foots - he can do them all. He is also incredibly fast.

Mbappe is the second most expensive player in history: Paris St-Germain paid Monaco £163m for him.¹ He earns £43m a year - but says that the money in football is "indecent".

In the last World Cup, he said he did not want to be paid. Instead, he gave his fee - over £350,000 - to a charity which organises sport for children in hospital.

He grew up in a Paris suburb, and comes from a sporting family. His father was a professional coach and his mother a handball player. They sent him to a Catholic school, and he is still a practising Christian.

He has always been ambitious. As a teenager, he learnt several languages so that he was ready to play overseas. His teachers remember him as intelligent and confident.

When he was 15, he designed a cover of Time magazine with a photo of himself on it. Four years later, he really did appear on the cover.

He has started his own charity to help children from the Paris area. He says he does not want to be "just the guy who shoots the ball and finishes his career and goes to the yacht and takes his money".

"I always say I dream about everything," he says. "I have no limits."

Yes: You will never get anywhere in life unless you aim high. Even if you do not manage to reach all your goals, you will still achieve more than you would have done if you never tried. 

No: Mbappe is clearly a one-off. It is fine to be ambitious if you are born super-talented, but most people are not, and aiming for things that are beyond your reach will only make you unhappy.   

Or... Everybody is good at something, whether it is languages or painting or playing football. As long as you focus on that and find people to encourage you, you will realise most of your ambitions.
