5 best U21 players in the world right now

#1 Kylian Mbappe

Easily the best youngster in the world, Kylian Mbappe is football's next superstar

There are some lists which have a surprise ending - but this one does not. Kylian Mbappe has already achieved the biggest trophy in football when he won the World Cup last year, and he was an integral part of the French team who accomplished this feat.

Otherwise, Mbappe has won the Golden Boy award, helped AS Monaco win a Ligue 1 title, and has already finished as the top scorer in Ligue 1 with Paris Saint-Germain alongside winning the Player of the Year Award. All this, before turning even 21.

Making his mark with Monaco, Mbappe moved to Paris Saint-Germain in 2017 for €180 million, making him the most expensive teenager of all time. The French international has already crossed the 100 goal mark in his career and has impressed in the Champions League too - having already netted 17 in the competition.

Not only is he by far the best player under the age of 21, Mbappe is one of the best in the world. Mbappe's pace, finishing, and link-up play have made him one of the deadliest forwards in the world.

It is but a guarantee that one day, Mbappe will wear the gold and white of Real Madrid, who are his dream club.

Regardless, Mbappe will be the torchbearer for the next generation of football, and his ceiling is incredibly high.
