The match comes on the same day Cristiano Ronaldo reportedly agreed to pay $21.8 million in fines and "serve" two years in prison for tax evasion though he isn't expected to actually serve any time.
Ronaldo made brief remarks to a Federation Internationale de Football Association press officer after the game but left before media could ask questions about his legal problems.
Cristiano Ronaldo expressed his delight at setting another record in his remarkable career as his hat-trick against Spain on Friday allowed him to become just the fourth player to score in four World Cups. Ronaldo was at the centre of the action as he was taken down in the box by Real clubmate Nacho - it was a dubious penalty, but the ref had no hesitation in pointing to the spot. Yet Spain responded superbly. "We will see how it goes because they have great players and if they can play as a team they can make a major impact".
Still, after the coaching chaos of the week, Hierro was willing to accept the draw.
"This is a mature team".
"We need to respect the work that has been carried out over the last two weeks in the run-up", the 50-year-old said.
The five-time Ballon d'Or victor, was named the world's most popular athlete by ESPN on the basis of his social media following, endorsement deals and search score.
Portugal appealed in vain for a foul on Pepe, but there was no intervention from the Video Assistant Referee.
Instead, Ronaldo stood with his legs apart in familiar pose, rolled up his shorts and curled an exquisite effort around the Spain wall and into the net past the helpless David de Gea.
Spain would recover and lead, only to concede a late equaliser as Ronaldo completed his hat-trick , but De Gea, 27, was relaxed about the result and his performance.
