The opening forty-five minutes turned into a tactical chess match punctuated by bruising collisions. Wales created the first genuine opening in the 14th minute. Neco Williams drove past Alexander Bah on the left flank, cutting back a low delivery that found Brennan Johnson. The Tottenham forward struck on the turn, but his effort skipped inches wide of the far post.
Denmark answered through structured possession. Eriksen dropped deep between the central defenders, pulling the Welsh double pivot out of position. In the 31st minute, Højlund broke free behind Joe Rodon, forcing Danny Ward into an outstretched kick-save. Wales responded with physical assertiveness, collecting two yellow cards before the break as the referee battled to keep control of fiery challenges in midfield.
