Neymar and Brazil arrive in Russia

Cristiano Ronaldo's off-night against Iran nearly cost Portugal their World Cup dream and underlined the stark need for his team-mates to contribute more in support of the Real Madrid superstar.

Ronaldo carried Portugal through their first two group games, hitting a memorable hat-trick in a 3-3 draw with Spain before netting the winner in a gritty 1-0 victory over Morocco.

That left the European champions requiring just a point from their clash with Carlos Queiroz's Iran in Saransk, but an uncharacteristic display from Ronaldo had them sweating over a place in the last 16.

The five-time world player of the year missed a penalty that would have given Portugal a 2-0 lead, Ronaldo was then perhaps fortunate to receive just yellow after an elbow on Iran defender Morteza Pouraliganji.

A disputed Iran penalty set up a tense final few minutes for Portugal, who only advanced to the knockout rounds after Mehdi Taremi fired a last-gasp chance into the side netting.

Qualification was at last assured, albeit with an upcoming tie against Uruguay rather than hosts Russia, but Ronaldo was far from impressed.

"I understand, it's normal. The best players in the world face that when there isn't an opportunity to really make it happen," said Portugal boss Fernando Santos.

"That hurts a lot more to them than to other players. They always want to win. They want to be the best and refuse to fail, and when they fail they get very upset."

Santos attempted to relieve some of the burden on Ronaldo by aligning Andre Silva alongside the Portugal captain in attack, with Ricardo Quaresma also handed his first World Cup start.

While Quaresma rewarded his coach with a stunning opening goal just before half-time, Silva offered little as Ronaldo found himself isolated and his opportunities limited.

Goncalo Guedes and Bernardo Silva were dropped after failing to shine in the opening two games, but Monday's performance showed Portugal are still scrambling to find the dynamic that best supports Ronaldo.

"There were lots of misplaced passes, the tempo was slow after the first 15 minutes," Santos said in the wake of the Morocco match. "Our team is strong but we must progress. We must do better than that."

Next up for Portugal is a Uruguay team, marshalled by the rugged centre-back pairing of Diego Godin and Jose Maria Gimenez, that has yet to concede in Russia.

"We have our weapons and we must try to make the most of them," Santos said on Monday.

Gelson Martins, the talented young winger who made a 30-minute appearance off the bench against Morocco, is another option who could be called upon going forward.

The question is not if Portugal have the weapons but whether they can be assembled in a way that plays to Ronaldo's strengths at his fourth and likely final World Cup.

Argentina legend Diego Maradona wished Lionel Messi on his 31st birthday through an Instragram post. Maradona posted a picture of him with Messi and captioned the image with a short dedication that read `Happy Birthday, Leo Messi’ accompanied by two emoji gifts:  a cake and an arm with a closed fist, as a sign of strength.

Maradona Supported Messi on his last match against Croatia, where the Argentine playmaker came under intense criticism from his countrymen.

Messi’s team mates and friends also celebrated his birthday, he was presented with birthday cake by Argentina team-mates as some of them posted some pictures with Messi on social media. Sergio Aguero wished Messi a happy birthday with a post on his Instagram. The 31-year-old also took time out to meet some of his team-mates' children.

Argentina are gearing themselves up for their final group game against Nigeria which will be held tomorrow at 12 pm in Bangladesh time.

A court in southern Brazil has forbidden ex-Barcelona striker Ronaldinho from selling 57 of his real estate properties due to an unpaid environmental fine and other debts, a Brazilian newspaper reported on Monday.

The Folha de S.Paulo paper said the former World Player of the Year owes 9.5 million reais ($2.51 million) in unpaid environmental fines after illegally building a pier at his lake house in Porto Alegre.

Creditors have also taken action to recover 7.8 million reais in other debts, Folha said.

Authorities have confiscated Ronaldinho's passport until the cases are resolved, the newspaper added.

The judge in Porto Alegre told Reuters the case fell under judicial secrecy rules and would not confirm or deny any details about the newspaper report.

Ronaldinho's lawyer denied the player's assets were under restriction but told Folha de S.Paulo he could not comment on the details of the case because of the judicial secrecy ruling.

The 39-year-old striker retired from football in 2015 after spells with a host of clubs in Brazil and Europe.

He was twice voted FIFA player of the year while playing for Barcelona and he also won the World Cup with Brazil in 2002.

The sports minister of Australia's state of Victoria reacted with anger on Thursday after Lionel Messi's Argentina pulled out of a highly anticipated June 11 friendly against rivals Brazil in Melbourne.

The event's promoter said it had been informed that Argentina were not prepared to travel to Australia for the match "contrary to their prior agreement and commitment to do so".

Ticket holders for the clash at Melbourne Cricket Ground, which would have come just five months before the World Cup, will be eligible for refunds, the promoter said.

"We are pretty disappointed and I think it's fair to say pretty pissed off," Victoria's sports minister Martin Pakula said.

"I think they owe Australian football fans an explanation because they have not provided an acceptable explanation to the promoter," he added.

"It's a game that would have been extremely popular here in Melbourne."

Melbourne is the capital of Victoria state.

In Rio de Janeiro, Brazil team coordinator Juninho Paulista said the cancellation of the friendly "greatly affects our preparation" for the World Cup.

Brazil want to find a replacement game during the June window, the penultimate one authorised by FIFA before the World Cup starts on November 21.

Veteran Argentina midfielder Javier Mascherano insists relations between the players and coach Jorge Sampaoli are not strained after reports of unrest within the team camp.

Sampaoli was roundly criticised for his game plan following a 3-0 loss to Croatia in Argentina's second group game at the World Cup, sparking rumours the 58-year-old would be sacked during the tournament.

"The relationship with the coach is completely normal," Mascherano said ahead of the must-win match against Nigeria in Saint Petersburg on Tuesday.

"Obviously, when we feel uncomfortable about something we speak with him because if we didn't we would be hypocrites."

Argentina were on the brink of elimination after the Croatia mauling but victory against Nigeria would send them through as runners-up in Group D if leaders Croatia avoid defeat against Iceland.

"We know the situation is tricky," Mascherano said. "We have to be united, to express our opinions, and do everything possible so the team goes into the game in the best position."

Argentine Football Association (AFA) president Claudio Tapia has given his backing to Sampaoli after holding a meeting with the embattled coach on Friday, a team source revealed.

Franco Armani is tipped to replace Willy Caballero for the Nigeria clash after the Chelsea goalkeeper's blunder against Croatia, with Sampaoli also expected to ditch his three-match defence and return to a traditional back four.
