Fourth minute of stoppage time, Kylian Mbappe suddenly explodes: climber on the right, an irresistible attack and the precise finish in the far corner - in Paris' Prinzenpark there is no stopping the world-class goal of the "alien".

Not the hapless Lionel Messi, not the trying Neymar, it was the sensational Mbappe who made the difference in Paris St. Germain's 1-0 (0-0) win in the Champions League round of 16 first leg against Real Madrid.

Mbappe, of course, who proved to his current and possibly future employers that he is an absolute difference player.

PSG are in an excellent position for the second leg on March 9th.

The French national player was "unstoppable", acknowledged Madrid coach Carlo Ancelotti, who wants to have the 23-year-old in his team from the summer.

Cost what it may.

“Mamma Mia. He's an alien.

It's a show with Kylian on and off the field," said PSG keeper Gianluigi Donnarumma on Sky Sport in amazement: "Mbappe will decide whether he wants to stay with PSG or not.

We enjoy every day with him.”

Only Mbappe, who continues to keep his plans a secret, knows how many days Donnarumma and Co. will be granted this.

He hasn't made his decision yet, said the striker after his show on Tuesday night.

But there are still many indications that he will fulfill his dream of moving to Real after the end of his contract in June.

"This match does not affect my future," said Mbappe: "I know that I play for one of the best teams in the world.

I will give everything for the rest of the season.”

This also applies to the fans of the French capital club, who paid homage to their hero.

Paris fired a total of 22 attempts at the goal of the strong Real keeper Thibaut Courtois – including a penalty from Messi (62nd).

However, only the incredible Mbappe could overcome him.

Given the oppressive dominance of the hosts, Real's midfield strategist Toni Kroos was able to live with the result.

"Even if it's unfortunate in the end, the result is still the best today," said the 32-year-old on Amazon Prime: "With the Bernabeu behind me, I won't rule anything out if it's 0-1."

Mbappe, world champion of 2018, also warned against too much euphoria with a view to the second leg.

"It's not over yet.

We know Madrid, they are among the best in the world,” said the exceptional player, who could soon switch sides.
