Matteo Guendouzi is the second-most valuable u20 player in Europe’s top five leagues, according to analysis by the CIES Football Observatory.

The Observatory put together a ranking based on their algorithm, which takes into account a number of factors including age, position, contract duration, minutes played and more.

Of all players born on or after January 1st 1999, Jadon Sancho ranked highest, which should surprise no one. The winger has 12 goals and 16 assists in 41 appearances this season, playing for one of the top teams in the Bundesliga. CIES gave him a value of €150.3m, far ahead of the rest.

After that, Matteo Guendouzi was second at €70.1m, after a solid debut season with Arsenal. To make 45 appearances in England and Europe after playing Ligue 2 football the previous campaign is no easy achievement.

There were a couple of other Arsenal entrants in the top 50, with Eddie Nketiah (€12.6m) in 35th place and Joe Willock (€9.8m) in 46th. The duo have just joined up with the senior squad on the trip to Valencia for the Europa League semi-final second leg, on the back of strong seasons with the academy.

Arsenal are likely to have quite a few more highly-valued youngsters in the coming years, given the recent success of the academy. The question is whether they can get that value out of them on the pitch or with transfer fees, or whether the club will mismanage them until they lose their value altogether.
