The Danes have already booked their spot in next summer's finals after winning eight and drawing one of their qualifiers and now face the second-placed team in Group H on the final matchday. The game will be played on Tuesday 17 November at the Ilie Oană Stadium, in Ploiești, kick-off 6.30pm.
Mads has featured five times for Albert Capellas's side this qualifying campaign, to add to 20 previous caps at Under-18 and Under-19 level.
With The Bees, Mads has made seven appearances this season. He played the full 90 minutes of our EFL Cup victories over Southampton, West Bromwich Albion, and Fulham and, until missing last night's draw at home to Swansea City, had featured in our previous four Sky Bet Championship fixtures.
