Holland coach Ronald Koeman says Inter Milan fullback Denzel Dumfries may miss the Euros.

Koeman says Dumfries' lack of games this season is a concern.

He told Goedemorgen Eredivisie: "With his contribution, the way he plays football, what he does, he is simply an important player for the Dutch national team.

"With Inter he has played little in the last few games, I don't know if this fact has to do with the extension of the contract.

"But we will have to evaluate the matter."
