Raphael Guerreiro says playing against Ghana was a difficult task as Portugal began their 2022 World Cup campaign with a 3-2 win on Thursday.

Cristiano Ronaldo opened the scoring for Portugal via the penalty spot after a goalless first half but Ghana improved after the goal and scored the equalised through skipper Andre Ayew from close range.

Portugal responded with two goals in two minutes to seal the points - Joao Felix converting a delightfully clipped finish and substitute Rafael Leao coolly stroking in just seconds after coming on. Osman Bukari headed in a late consolation for Ghana and there could have been real drama in the ninth minute of stoppage time.

"In the end, it was very difficult, but the most important thing was the victory. Now let's focus on the next game," Guerreiro said after the game

"Yes. If we win the next game, we qualify. We're on the right track. On the way to being champions? Right."

The defeat means the Black Stars are bottom of Group H after Uruguay and South Korea played out a goalless draw earlier on Thursday.

The Black Stars will now switch their attention to the match against South Korea on Monday before taking on Uruguay on December 2 at the Education City stadium.
