Portugal began well and generated the better opportunities. At 41, Ronaldo displayed glimpses of his constant threat; a fantastic diving stop from Unai Simón stopped him, however.
Standing tall for Portugal, Diogo Costa made two important second-half saves to maintain the score level, while defenders such as Ruben Dias made crucial blocks.
Still the assault lacked cohesiveness. João Félix and others battled to connect play efficiently.
Expected to lead from midfield, Bruno Fernandes neglected what he does best: penetrating passes and innovative spark.
As the game got close, his impact diminished; Ronaldo was left alone despite Portugal perhaps having a better midfield on paper than Spain, with players in great club form.
Growing into the match, Spain dominated possession and threatened through Dani Olmo and Lamine Yamal. Their defense stayed very strong, which helped them to extend an amazing run of clean sheets.
Pressure sustained over the late goal came as Merino sent Spain through by taking advantage of a set-piece or scramble.
Portugal’s midfield advantage and Ronaldo’s presence notwithstanding, familiar knockout weaknesses came back to haunt them. Their talisman exits once more at the Round of 16, a letdown.
Spain moves forward, their strategic discipline and young enthusiasm making all the difference in a game of close margins. Though Ronaldo’s legacy continues, this chapter finishes without the fantasy farewell many wished for.
