Kylian Mbappe must learn to "walk on fire" if he wants to achieve his full potential, according to Zlatan Ibrahimovic.

France striker Mbappe is in his fifth year at Paris Saint-Germain and the 22-year-old has been the team's Ligue 1 top scorer in the past three campaigns.

Mbappe continues to be linked with a move to Real Madrid, which could happen at the end of this season, given he will become a free agent if he refuses a new PSG contract.

Former PSG frontman Ibrahimovic, who famously scored 38 league goals in the 2015-16 season, feels there is more to come from Mbappe if he introduces a greater edge and stretches himself to the limit.

Ibrahimovic has been a master of tacking his talent to an exuberant, at times brash, character, and it has made him an opponent that others fear, not merely for his goal threat but his force of personality.

He told Telefoot: "I love Mbappe, but what he does is not yet enough. He is too comfortable, in his zone. He needs to walk on fire and then he will be even better.

"He needs to sense the taste of blood. You have to be surrounded by those who tell you you're not good enough and you can progress, not by those who say you're the best."

Mbappe has become pivotal to PSG since arriving, initially on loan, in 2017 from Monaco.

Kylian Mbappe has a sharp eye for goal

Last season there was a marked difference in PSG's fortunes when he was not in the team. With Mbappe starting, as he did in 27 Ligue 1 games, PSG averaged 2.3 points per game, winning 74 per cent of those fixtures, but in the 11 matches when he was absent from the XI those numbers dipped to 1.8 points per game and a 54.5 per cent win rate.

Given PSG were pipped to the title by one point, as Lille were crowned French champions, his importance becomes obvious.

Including appearances off the bench, he featured in 31 Ligue 1 games and scored 27 goals, his second-best return for the Parisians, beaten only by his remarkable 33-goal effort in the 2018-19 season.

Mbappe will have his work cut out to match Ibrahimovic's 2015-16 strike rate of one goal every 67.2 minutes, although he has had three campaigns so far where he has dipped under the goal-every-90-minutes bar.

"Mbappe is in the top category of those that I like," said Ibrahimovic. "There are other players who have been at the top for a long time. Among young people, there is Mbappe, [Erling] Haaland. And who else? There is Ibrahimovic, no need for anyone else."
