The decision to introduce the rule around covering your mouth was taken during a special meeting of the International Football Association Board (Ifab) in Vancouver in April.

The issue of players covering their mouths became high profile in February when Benfica winger Gianluca Prestianni raised his shirt while speaking to Real Madrid's Vinicius Jr during a Champions League game.

The Argentina international was accused of racist abuse - which he denied - and provisionally banned for one match. Following a Uefa investigation, Prestianni was instead found guilty of homophobic conduct and banned for six matches - three of which were suspended.

The new rules that were set for the World Cup were implemented in this game too as Paraguay's Miguel Almiron became the first player to be shown a red card for covering his mouth.

Almiron obscured his mouth with his hand while speaking to Turkey's Mert Muldur, who immediately informed an official standing next to him.

Following a check by the video assistant referee (VAR), referee Ivan Barton from El Salvador announced to the crowd that he was sending off the former Newcastle United winger.

The incident occurred just before half-time with Paraguay leading 1-0.

Vincenzo Montella's side have failed to score so far at this World Cup despite attempting 62 shots - which, according to Opta, is the most attempts without a goal in any two-match span in the competition on record (since 1966).

Not only did Turkey have a ridiculous amount of chances, they also dominated the ball in both their games.

Against Australia, they had 71.6% possession and against Paraguay it was 78.5%. They were helped in the second game by the fact they were facing 10 men, but they were the dominant team even before Almiron was given his marching orders.

They also had a higher xG than their opponents in both games with 1.33 in the game against Australia, who had 0.77 but scored twice.

Their xG against Paraguay was 2.1 to the South Americans' 0.32. And they had more than 100 touches in their opponents' penalty area across the two games.

For 180 minutes they have attacked, entertained - and done almost everything other than score.

The critical eye would point to the fact they had just 13 shots on target across the two games.

Yet it is remarkable, given the share of play they have had, that they have not scored in two games - and are heading home no matter the result against USA next week.

Paraguay took the lead after just 64 seconds when midfielder Matias Galarza fired in from outside the area to score the fastest goal so far in this tournament and what turned out to be the match-winner.

Almost from that point onwards, however, it was one-way traffic as Turkey piled forward in search of an equaliser.

Despite their complete dominance, Turkey managed just one shot on target from 12 attempts, while a deflected header from Mert Muldur hit the bar and the post.

Turkey had 30 attempts on goal against Australia in their first game and a further 32 here but could not find a way through against the 10 men in the second half and remain goalless in this tournament.

They cannot progress now after two defeats, while Paraguay know if they beat Australia in their final Group D game, then they will be through to the knockout stages.

A pretty miserable World Cup for Turkey.

For those of you that missed the match, here's the highlights.

Did anyone stay up to watch the game?

Kudos if you did, I was fast asleep ...

As you can see, USA top Group D with a perfect six points from a possible six.

Sticking with this group, Paraguay beat Turkey in the 04:00 BST kick-off to boost their last 32 hopes and eliminate Turkey from the competition.

The US have scored six goals in their two matches at this year’s World Cup. They’ve only scored more over an entire tournament twice (seven in 1930 and 2002).

Back in September 1996, Antonio Freeman's performance lit up the American football stage as his two touchdowns helped the Green Bay Packers to an impressive win at the Seattle Seahawks.

Months later he became a Super Bowl winner - the highest accolade an NFL player can achieve.

Fast forward almost 30 years and the name Freeman is creating headlines in Seattle once again but this time in a different sport, with his son Alex scoring his first World Cup goal on Friday to help the USA to a 2-0 win against Australia to seal their place in the knockouts.

"It's a full circle family moment," Alex Freeman said after the win.

"It shows how great the family tree is. It shows he can be great but I can be great in my own way and how amazing it is to have a dad that is successful and can mentor me to be ready for moments like these."

Freeman senior is following his son every step of the way on this World Cup journey, having been seen beaming with pride at USA matches.

Australia have conceded three own goals in their World Cup history (also in 1974 and 2018), only Mexico (four) have conceded more (Bulgaria, Morocco and Switzerland also three).

Another win for the US and another dominant performance that impressed.

Whether the rivalry between the United States and Australia is genuine or just a media fabrication, it was clear that the hosts were fired up from the start in Seattle.

While their opening-game victory against Paraguay was impressive, this was arguably the first time in Pochettino's tenure the US looked a team entirely in his image.

After twice losing possession in their own third during a nervy opening few minutes, the tournament co-hosts set about relentlessly pressing Australia high up the pitch.

Their early goal put Australia on the back foot, and means they are the first World Cup hosts since France in 1938 to score in the first 15 minutes in each of their first two matches of the tournament.

Australia spent much of their win against Turkey without the ball, but in the first half in Seattle they hardly had time to breathe, never mind get on the ball and do something meaningful with it.

Balogun was once again a livewire up front, while midfielders Weston McKennie and Malik Tillman constantly made dangerous runs in between the Australia centre-backs and wing-backs.

The tone for this most all-American of performances was set before kick-off when the 67,000-strong crowd at Seattle Stadium belted out Star Spangled Banner with as much gusto and enthusiasm as you are likely to see this summer.

The US had not played in the state of Washington since 2016, but have now won each of their past eight games played in Seattle - and will return here in the last 16 if they win their last-32 game in Santa Clara.

Judging by the way the crowd and players fed off each other, they will be eager to come back.

We'll move away from Scotland reaction now and take a look at what happened in the other three matchday nine games.

First up is USA's win over Australia ...

BBC Sport Scotland in Boston

And with that, Scotland’s great love affair with Boston is brought to an end. For now.

It’s been beyond magic. Beer, baseball and brotherhood has united the Bostonians and the visiting Scots to the degree neither want to say ta-ra to the other.

Saltires will no longer sail along the streets, bagpipes won’t be their soundtrack and the name John McGinn won’t be mentioned on every corner.

There’s a chance if Scotland create history and reach the knockout stages that they’ll be back here later this month.

The stuff of dreams for many…

There's been moments of frustration, moments you wish we could control better. But the reality is these tournaments are never easy. It's never easy playing the best teams in the world.

Brazil will pose a different challenge but it's another opportunity to make history. On the face of things, it feels like we've learned lessons.

I've enjoyed the bravery as the games have gone on, and bravery is what epitomised that performance in the second half.

From the worst start to a hopeful and promising end, Steve Clarke's side will carry that hope into their final group game against Brazil on Wednesday – live on the BBC – as they go for history.

Midfielder Ryan Christie, speaking to BBC Scotland: "Had we played another five minutes, we might just have had them.

"It's frustrating. The start to the game wasn't exactly how we planned it. It would have been easy to chase the game and get a bit disjointed. But we limited them to very little second half and started to play our football.

"It just wasn't to be.

"I've thought the one on McGinn could have been a penalty, I had a good view of that. There wasn't many fouls getting given out there, to be honest.

"We need to take confidence. The immediate feeling is frustration and disappointment. This group of boys will bounce back, we're so together.
