Kasper Hjulmand's side are in Group B alongside Finland, Belgium, and Russia. As one of the host nations, The Danes will play all their games on home soil at the Parken Stadium in Copenhagen.
They begin on Saturday 12 June against Marcus Forss' Finland, kick-off 5pm, before playing Belgium in their second game five days later, also a 5pm kick-off. They finish their group campaign, after which the top two and four of the six best third-placed sides go through to the knockouts, against Russia on Monday 21 June, kick-off 8pm.
All of Christian and Mathias' senior Denmark caps have come this campaign. Christian, who picked up the Man of the Match award on debut against England last September, has four appearances to his name while Mathias has played five times for his nation, netting his maiden international goal in March's 8-0 World Cup Qualifying win over Moldova.
At Club level this season, injury has restricted Christian to 22 appearances in all competitions. He featured 17 times in the Sky Bet Championship and played four of our games en route to the Carabao Cup Semi-Final, netting in the 2-0 win over Southampton in Round Two. Mathias has been an almost ever-present, featuring 52 times this campaign. He has netted twice this term, those goals coming in the 3-1 home win over Reading and the 4-1 victory at Middlesbrough.
