Portugal and Spain played out an enthralling goalless draw in their first encounter since that memorable match at the 2018 World Cup.
On that night in Sochi, Cristiano Ronaldo scored a hat-trick but there was no way through for the Portugal captain on Wednesday night in Lisbon, though he came closest with a stunning left-footed drive which hit the bar in the second-half.
Joao Felix missed a close range sitter in the closing stages and Renato Sanches also rattled the woodwork in a game where Spain dominated the ball, but it was a pair of Premier League keepers in Kepa Arrizabalaga and Rui Patricio who will go home the happiest after bagging clean sheets.
