Netherlands midfielder Teun Koopmeiners was expected to star for his country at Euro 2024, but instead is left rueing a "nightmare" injury that has ruled him out of the tournament.

Koopmeiners was an integral figure as Atalanta secured their first-ever European trophy this term, beating Bayer Leverkusen in the Europa Conference League final last month.

With Ronald Koeman already missing Barcelona's Frenkie de Jong for the upcoming tournament in Germany, the Netherlands boss was dealt another blow on Tuesday.

Koopmeiners took to Instagram to confirm his absence for UEFA's 17th edition of their flagship competition after his injury in Monday's warm-up victory over Iceland.

"What should have been a wonderful month has unfortunately turned into a nightmare," wrote Koopmeiners.

"With great disappointment and sadness, I heard the results of the tests. Unfortunately, they found I have no possibility of participating in the European Championship 2024.

"Playing for the Dutch team at a finals tournament and with such a great squad would have been a great honour.

"From now on, like the rest of the Oranje fans, I will encourage and support the team on their way to a great tournament!"

Koopmeiners, a reported target of Juventus and Liverpool, has appeared 21 times for his country as Oranje supporters grew hopes of a fearsome partnership with De Jong in midfield.

Atalanta team-mate Marten de Roon has already been ruled out through injury, leaving Koeman short on options in the middle of the pitch.

In response to the absence of the two players, Koeman has called up Borussia Dortmund loanee Ian Maatsen, who returns after initially failing to make the Netherlands' final Euro squad.

The Netherlands open their campaign against Poland on Sunday before facing France and Austria in Germany.
