Subtitute Merino scores late winner as Spain knock put Portugal

Mikel Merino came off the bench to score an injury-time winner for Spain as they knocked Portugal - and Cristiano Ronaldo - out of the World Cup in a heavyweight last-16 tie in Dallas.

The five-time Champions League winner has said this would be his final World Cup, while, before last week's last-32 game with Croatia in Toronto, Ronaldo's sister stated this tournament would be his "last dance".

Roberto Martinez's side continued to grow into the game after the break, though Ronaldo cut a frustrated figure up front in a second half that produced little in the way of action in the final third.
