Previous Kaizer Chiefs and Orlando Pirates coach Mohsin Etugral said Ghana had no chance of qualifying from their World Cup group.
The Black Stars are in Group H with Portugal, South Korea and Uruguay.
While assessing the strength of the two sides, Ertugal did not give the African representatives any chance to get a knockout ticket.
The Turkish tactician also added that Ronaldo’s Brazil could make it all the way to the quarter-finals.
“Portugal are an interesting team,” Etugal said.
“Years ago it was always a one-man show, they always had unbelievably good talent and players, but are they capable of reaching a certain level? I might see them in the quarter-finals, But it’s not over yet, this team isn’t enough,” he said.
“For me, Ghana has no chance in this group, no chance.
“Maybe Uruguay. South Korea is interesting. For the last few years they always started Kim Min-jae, he was with Fenerbahce and now with Napoli. He’s a great, great defender and they have Lots of defenders like that.
“So South Korea could end up being a surprise.”
The Black Stars were recently encouraged by a 2-0 win against Switzerland after entering the Global Championship. West Africa lost 3-0 to Brazil in a friendly in September and then beat Nicaragua 1-0.
Their star midfielder Thomas Partey was absent from these friendlies. He was unable to participate in Ghana’s friendlies against Brazil and Nicaragua due to injury.
The Arsenal star was in the matchday squad for the win over Switzerland on 17 November but was an absent substitute.
Ghana, meanwhile, suffered a setback with goalkeepers Joe Waracott and Richard Ofori left out of the Global Regals through injury.
The Black Stars begin their World Cup campaign on November 24 against Portugal. They will then face South Korea before finishing the group stage with a game against Uruguay.
