World Cup diary: Day 9 - Ronaldo's invisible touch, Casemiro gets Brazilian samba going and goals galore for Cameroon, Serbia, Ghana and South Korea

The eighties' classic Invisible Touch by Genesis provided the soundtrack for Cristiano Ronaldo's latest footballing controversy on day nine of the Qatar World Cup.

Ronaldo's Portugal marched into the knockout stages following their 2-0 victory over Uruguay in the Lusail Stadium on Monday night.

But not content by becoming the first footballer ever to score at five World Cup finals, CR7 needed one more to equal Eusebio's record as Portugal's highest scorer on the greatest stage and he laid a cheeky claim to it in his latest match.

Former Manchester United team-mate Bruno Fernandes curled the ball into the Uruguay penalty area and Ronaldo leaped to head it goalwards, but clearly didn't as the ball scraped past his head and flew directly into the goal.

The goal was initially given to Ronaldo but the camera doesn't lie, and every angle shown on TV suggest otherwise.

Not surprisingly, the superstar has claimed it, making a skimming action against his head to tell the watching world that there was indeed a touch invisible to the naked eye.

Certainly one of the greatest players in football history, Ronaldo doesn't need to bag phantom goals to enhance his reputation any further. Who knows, he may have felt the buzz of a Qatari mosquito whizzing by his noggin.

It wasn't the game's only controversy.

VAR reared its ugly head for the second Portuguese goal, a ridiculous penalty award when Uruguay defender Jose Gimenez planted his hand into the ground to support his body as he fell. The ball ran through his legs, accidentally struck his hand and the spot kick was given.

Football will be ruined if the guidance behind these video-assisted calls doesn't change. It has already been diminished as a spectator sport, and moments like this will turn supporters away.

Fernandes duly slotted home the penalty - this time Ronaldo did not claim a touch - and Portugal were into the last sixteen.

Brazil had already confirmed their qualification from Group G with a narrow, but well-deserved victory against Switzerland.

Even without the injured Neymar - who is expected to return for the knockouts - the canary yellows had just too much for the stoic Swiss.

Samba beats were silenced when Vinicius Junior's clinical 64th minute strike was disallowed for offside by VAR.

A goalless draw wouldn't have been a disaster for Brazil but they found a late winner when Manchester United's Casemiro connected beautifully with a shot that flicked off the bum of Switzerland defender Manuel Akanji and fizzed into the net.

Monday started with a World Cup classic between two of the competition's minnows.

Serbia and Cameroon both lost their opening match and knew a victory could heighten their chances of qualification to the last sixteen.

Before a ball was kicked, Cameroon manager Rigobert Song decided to drop his first-choice goalkeeper Andre Onana for disciplinary reasons, bringing in Devis Epassy just before kick-off.

The new goalie was barely tested during an uneventful first half hour and Jean-Charles Castelletto broke the deadlock for the African nation.

The Indomitable Lions' challenge seemed to cave in after that, losing two in quick succession followed by a third from the deadly boot of Premier League star Aleksandar Mitrovic.

The Serbians were looking good at this stage, but sub Vincent Aboubakar entered the fray for Cameroon and scored a goal before setting up Eric Maxim Choupo-Moting two minutes later to make it 3-3.

Disappointingly, the scoring was completed after 66 minutes but it was a thrilling spectacle in stark contrast to so many of the goalless bore draws.

The thrills kept coming when Ghana took on South Korea at the Education City Stadium.

Mohammed Salisu fired the Africans ahead and powerful Ajax raider Mohammed Kudus added a second before half-time.

The Koreans were still a lively attacking threat and striker Cho Gue-Sung netted twice in three minutes to bring the scores level.

Kudus quickly restored Ghana's lead which they held until the end, with some of the South Korea team in tears as they left the pitch.

Their manager Paulo Bento was also crying, but more in rage as his team had won a corner kick when English ref Anthony Taylor blew the whistle.

A red card for Bento completed a day of despair for the South Koreans.
