Kylian Mbappe is no longer the most valuable player in world football

Paris Saint-Germain superstar Kylian Mbappe is no longer the world's most valuable football player, losing his top spot in a new study.

The 23-year-old is regarded as one of the world's best players, having already won four Ligue 1 titles and the World Cup.

Mbappe's value on Transfermarkt is currently £140 million. It would likely cost more than that to get him out of the Parc des Prices anytime soon, though.

He's slipped down the pecking order due to one man in particular's sensational start to the season.

Manchester City striker Erling Haaland has scored a whopping 23 goals in all competitions, returning from injury to score the winner against Fulham on Saturday.

The Norway international, who only cost City £53 million in the summer, is valued at a staggering £148 million. That's £8 million above Mbappe at the time of writing. It feels like these two are destined to do this forever already.

Mbappe's had a spectacular start to the campaign in his own right. Despite rumours suggesting he's ready to leave PSG as early as this January, the forward has scored 18 goals in 19 appearances to help PSG remain unbeaten.

Meanwhile, Haaland is on track to smash a number of Premier League records. He's already scored the same number of goals as Cristiano Ronaldo managed last season. Worth keeping in mind Ronaldo finished the Premier League's third-highest goalscorer and we're currently in November.

The 22-year-old still isn't 100 per cent after a recent foot injury and illness. City return to action against Chelsea in the Carabao Cup on Wednesday with manager Pep Guardiola remaining coy on his star striker's involvement.

"He's not perfect still," the Spaniard told reporters in his pre-match press conference. "So we'll see tomorrow and next Saturday but he's getting better.

"The important thing is that the bone is not broken, it's not damaged. It's just the ligaments that are damaged a little bit.

"It's not perfect right now but in a week or ten days, everything can change. If he feels good he can play with the national team, it's so important for the players. I never worry about the players when they are fit to play with the national team."
