#1 Matthijs de Ligt
Ajax's centre-back is among the best young defenders in Europe right now, and he has already been capped 13 times for Netherlands' senior team despite being just 19 years of age.
Matthijs de Ligt has been with the Amsterdam-based club since the age of nine, and he made his senior debut during the 2016-17 season. He impressed in the 11 appearances he made that season and won the AFC Ajax Talent for the Future 2016 accolade for his performances.
The Dutch international continued his growth the following season and cemented his place in the Ajax starting XI. He played 33 league games during the 2017-2018 season and won the AFC Ajax Talent of the Year 2018 award along with the Dutch Footballer of the Year Bronze Boot.
The 19-year-old has been being linked with a move away from the Ajax arena the last few weeks, and it will be interesting to see whether Ajax will be able to keep hold of their talented youngster beyond the January transfer window.
