Cristiano Ronaldo is preparing to lead Portugal into their opening Group H game against Ghana on Thursday.

"I'm feeling great, I'm recovered and I'm training well and ready to start the World Cup in the best way possible," said Ronaldo.

"I feel that this Portugal squad has amazing potential. I think we can win for sure, but we need to focus on the next game. So, it's focusing in Ghana, get a win and go from there.

"We will see in the end who the best team is, but I believe Portugal is the best team in this World Cup. But we need to show it on the pitch."
