Portugal 1-0 Switzerland
This is a cracker.
Switzerland, despite falling behind, have responded well.
Confusion around the Portuguese penalty area almost lets in Xherdan Shaqiri who is proving to be a real menace.

Bit harsh that, Chris.
Thought that was a class finish to be honest.
Cristiano Ronaldo has scored 86 goals for Portugal. Let that sink in for a minute...

It was dreadful goalkeeping but how many times have we seen Cristiano Ronaldo make his mark? He scores on the goalkeeper's side as Yann Sommer is rooted.
Now Switzerland have to respond.
Cristiano Ronaldo
It just had to be him, didn't it?
A screamer of a free-kick!
Portugal are awarded a dubious set-piece about 25 yards out and there's only one man standing over the ball.
Cristiano Ronaldo steps up to send a vicious, swerving ball into the corner of the net.
Absolutely sublime.

Switzerland are very capable and they look a threat. Xherdan Shaqiri has started this game really well and he looks up for it.
Ruben Neves needs to get in and around him to stop him from getting his head up.

Cristiano Ronaldo has not scored in any of his previous four appearances for Portugal, since the 2018 World Cup.
He's still cursing his earlier miss. Unbelievable by a player of his very high standards.
Portugal 0-0 Switzerland
This isn't going to finish 0-0. There, I've said it. This is just the kind of end-to-end game bosses of the Nations League finals wanted.

What a ball in from the right hand side. Xherdan Shaqiri fizzes a ball across the face of goal and it's a big miss for the Swiss. Any sort of touch there and they take the lead.
Portugal 0-0 Switzerland
How is this still goalless?
Xherdan Shaqiri whips in a delicious delivery across the face of goal. It just needs a white shirt to make a connection.
Portugal escape and Shaqiri can't believe his ball has not ended in the back of the net.

If you wanted that chance to fall to anybody it would be to Cristiano Ronaldo. He is 18 yards out with just the keeper to beat but he pulls it horribly wide.

A horrible pass by Manuel Akanji just outside the Swiss penalty area leads to a glorious chance for Cristiano Ronaldo but he puts it wide.
That's a bad miss by his standards.
Chances at both ends now. This certainly isn't a cagey affair.
Portugal 0-0 Switzerland
Another meaty challenge.
This time Swiss captain Granit Xhaka clatters into Nelson Semedo.
Perhaps Xhaka is still upset a week after Arsenal's Europa League final capitulation.

I think Bruno Fernandes is naughty there. He appears to pull out just at the last moment and that may have saved him.
Portugal 0-0 Switzerland
Crunch!
Bruno Fernandes goes in hard on Kevin Mbabu and gets a long lecture from the referee for his actions.
No card though.

Has Cristiano Ronaldo touched the ball yet?

Switzerland reached the finals after finishing above World Cup semi-finalists Belgium in their group, and they've made a lively start in Porto against the much fancied hosts.
Haris Seferovic is posing plenty of early problems.
Portugal 0-0 Switzerland
First chance and it falls to the Swiss.
Xherdan Shaqiri, fresh from spending 90 minutes on the bench in the Champions League final, finds himself through with only Rui Patrício to beat but the Wolves keeper stands tall to save with his foot.
That was close.
Portugal 0-0 Switzerland
Portugal, roared on by a partisan crowd, come flying out of the blocks.
The hosts are pressing right from the off and Switzerland are struggling to get out of their half.

The inaugural Nations League finals are under way.
There's a minute's silence for former Uefa president Lennart Johansson, who oversaw the introduction of the Champions League, who has died aged 89 following a short illness.
