Striker Kasper Dolberg scored twice either side of the half time break and late goals from Joakim Mæhle and Martin Braithwaite wrapped up the result as Denmark looked the better side throughout. Wales was limited to half chances by a stout Danish defense, with Gareth Bale coming closest early in the encounter, but his effort just went wide of the post. Harry Wilson received a red card late on for a cynical challenge. Denmark’s qualification for the quarterfinals comes two weeks after its star midfielder, Christian Eriksen, suffered a cardiac arrest during its game against Finland in the group stages. Eriksen has since been discharged from hospital after undergoing a “successful operation” and having been fitted with an implantable cardioverter defibrillator (ICD).”It’s completely crazy,” Dolberg told DR afterwards. “I actually don’t know how I feel. This is total madness. It’s surreal. It was here it all started for me, and to play here again in this setting was insane.”Read MoreREAD: Euro 2020: Kasper Schmeichel recalls Christian Eriksen’s first visit to training following collapseDenmark’s Dolberg celebrates with teammates after scoring his side’s second goal against Wales.
