Football the focus as Portugal face Ghana

Portugal will be keen to let their football do the talking when they face Ghana in their World Cup opener amid controversy over Cristiano Ronaldo's criticism of Manchester United and tensions between the squad and the media.

Euro 2016 champions Portugal hammered Nigeria 4-0 in their last warm-up match before flying to Qatar, offering some encouragement after a poor run of form.

Ghana - who reached the World Cup quarter-finals in 2010 - arrived on the Arabian Peninsula with the wind in their sails, too, after beating Switzerland 2-0 in a friendly.

Thursday's meeting (3am Friday AEDT) at the 974 Stadium in Doha gives the sides the chance to lay down an early marker in Group H, which also includes Uruguay and South Korea.

Portugal coach Fernando Santos has come under pressure from local media and fans following recent disappointments - including a last-16 Euros exit last year.

There is also talk of tension in the squad and worries among fans that the team is too focused on serving captain Ronaldo, who at 37 is past his prime.

"The environment in the changing room is excellent. No problems," five-times Ballon D'Or winner Ronaldo said on Monday.

"The group is shielded. And I take this opportunity to say: stop asking about me."

But the chances of Ronaldo disappearing from the spotlight look slim in the wake of an explosive TV interview in which he said he had been betrayed by Manchester United, leading to his immediate departure from the club.

He led Portugal to triumph at Euro 2016 but World Cup glory has eluded him and Qatar represents his last chance.

Some fans say the time has already come for Ronaldo to step aside and let talent such as Manchester United pair Bruno Fernandes and Diogo Dalot, and Manchester City's Bernardo Silva, Ruben Dias and Joao Cancelo, take centre stage.

Lining up against them for Ghana are likely to be Arsenal midfielder Thomas Partey, Leicester City defender Daniel Amartey and Athletic Bilbao striker Inaki Williams.

Coach Otto Addo, Ghana's third manager in 12 months, has sought to rebuild the team after a disastrous showing at the Africa Cup of Nations in early 2022, bringing in more Europe-born players such as Brighton & Hove Albion wingback Tariq Lamptey.

But his plans suffered a setback when both of his leading goalkeepers suffered injuries, meaning third-choice Lawrence Ati-Zigi - who plays at St Gallen in Switzerland - will be entrusted to keep out Ronaldo and his colleagues on Thursday.

The teams met at the 2014 World Cup in Brazil when Portugal won 2-1 thanks to a late winner by, you guessed it, Ronaldo.
