RESULT: Portugal 6-1 Switzerland - Goncalo Ramos, who replaced Cristiano Ronaldo in the starting XI, scores a hat-trick. Pepe, Raphael Guerreiro and Rafael Leao also on target
Manuel Akanji scores consolation goal for Switzerland
Portugal will face Morocco, who beat Spain on penalties in their last-16 match, in the quarter-finals on Saturday
Goncalo Ramos
The man who replaced Cristiano Ronaldo scores!
Goncalo Ramos marks his first international start with a brilliant goal. From a throw, he is picked out inside the box by Joao Felix, the angle is very tight but somehow Ramos finds the only place the keeper didn't have covered, hammering into the roof of the net just inside the near post.
What a finish.

I think the loudest cheer of the night will be when Ronaldo comes to warm up and gets up out of the dugout.
Portugal 0-0 Switzerland
A quarter-of-an-hour gone and it is has been an even encounter that is yet to spark into life. The wave of noise going round the stadium means a Mexican Wave has started.

Can Portugal do without Ronaldo? Yes they can. Look at how the Euro 2016 final turned out without him for the majority of that match.

No real strikes on goal at the moment, it's what we were expecting.
Portugal 0-0 Switzerland
Not sure how warm it is down at pitch level tonight but Ricardo Rodríguez and Edimilson Fernandes will be ticking over the kilometre count.
The wingers drop into a back five when Portugal have the ball but are then quick to get up and support the attack when Switzerland win it back.
Portugal 0-0 Switzerland
Incredible amount of focus on the Portugal bench before kick-off.

The Portuguese 'Iceland clap' is happening...
Portugal 0-0 Switzerland
A great ball out to the right flank by Ruben Vargas but Edimilson Fernandes then puts too much on his ball into the box and it goes out of play.
Portugal then lose possession just outside their own box but Xherdan Shaqiri is unable to capitalise in time.
A good spell for Switzerland.

When Switzerland do get the pass deep in their own half, the press from Portugal is really clever, down to the direction of how they are pressing. They've really got the pressure on Switzerland.
Portugal 0-0 Switzerland
Switzerland are looking much more comfortable in possession now, particularly down the left. Pepe goes in a bit too strong on Xherdan Shaqiri for the referee's liking and the Swiss have a free kick around halfway.
A steady opening few minutes.

It's just interesting to see how Switzerland cope. They haven't had a lot of possession so far and they won't mind that. The way Portugal have started the game on the ball, they look so comfortable.
Portugal 0-0 Switzerland
Breel Embolo, despite that early knock, is looking dangerous. He does well on the edge of the area to open up a bit of space for himself but then Pepe puts himself in the way of the shot when it comes. The ball goes out for a corner but it comes to nothing.
Portugal 0-0 Switzerland

All the noise is coming from the Portugal fans behind the goal to our left. They have a few different musical instruments with them. The Swiss contingent are mainly on the far side and they were chanting loudly before kick-off.

Breel Embolo is caught by Ruben Dias' stray arm and is in some discomfort just off the pitch. He wants a free kick but it will be a Portugal throw.
Portugal 0-0 Switzerland
A good start by Portugal, switching the play well as they look to find the gaps.
Joao Felix knocks the ball to Bruno Fernandes inside the box but his first touch is a heavy one and Switzerland clear.

Cameramen absoutely swarming the Portugal dug-out after the national anthems to get their shots of the dropped Cristiano Ronaldo.

The final game of the last 16 is under way.
Will Portugal get the job done without Cristiano Ronaldo? Twenty-one-year-old Goncalo Ramos of Benfica, who has played 33 minutes for Portugal, is the man to take his place in the side.

Image source, .Switzerland were really passive against Brazil and didn't manage a shot on target, but their other games in Qatar give us a better idea of what to expect from them here.
Portugal have some excellent players but the Swiss will be full of confidence after the way they overcame Serbia to get to the last 16. They also beat Portugal when they played them in the Nations League in June.
This will be close and I have a feeling Cristiano Ronaldo will have a big say in the outcome - although not necessarily in a positive way.
Sutton's prediction: 1-1 - Switzerland to win on penalties after extra time, with Ronaldo missing the decisive spot-kick.
