Ghana striker Asamoah Gyan is winning his battle to be fit for Friday's quarter-final clash with Uruguay in Johannesburg.
The 24-year-old has been forced to sit out his country's last two training sessions with an ankle problem sustained during the win over the United States in the last-16 meeting.
But the Rennes player is confident he will be ready to try and improve on his tally of three goals in four games in South Africa.
Gyan, speaking after tonight's training session near Rustenburg, said: "The ankle is getting better. I had a knock during the game last time.
"Yesterday I felt something bad and I had to go out (of training) and rest today as well.
"But tomorrow I think I will be fine.
"I will be fine for the game on Friday. It is nothing really bad. I need about two days off and I will be fine."
Gyan scored from the penalty spot against Serbia and Australia and netted the extra-time winner against USA.
He is confident Ghana can overcome Uruguay and secure a place in the semi-finals.
He said: "Uruguay are a difficult side but we don't care who we are going to play against. We are ready to play against anybody."
Meanwhile Inter Milan midfielder Sulley Muntari wants to "leave all the negative stuff behind" as he prepares to make his first start of the tournament against Uruguay.
The former Portsmouth player came close to being sent home after a dressing room row with Ghana coach Milovan Rajevac after the game with Australia.
But he patched up his differences with Rajevac and the suspension of Andre Ayew means Muntari is likely to play.
He said: "I always give 100% to the team. It is going to depend on the coach who plays but I am always ready to give my all.
"On a personal level I want to leave all the negative stuff behind me."
Muntari admitted: "I had a discussion (with Rajevac). I think I was maybe a little silly.
"Everything is good now, everything is cool.
"It is a happy moment for us that we are in a World Cup quarter-final but all of us have our feet on the ground.
"We always show dedication and commitment."
