Ghana goalkeeper Adam Kwarasey says he is happy to be regaining his form after his nervy start at the 2012 Africa Cup of Nations.The 24-year-old shot stopper, who is making his tournament debut in Africa's flagship competition, has been criticized for his role in conceding a goal against Guinea in the final group game.Some have also questioned the Norway-born keeper's aerial judgments.However, Kwarasey saved Ghana's blushes in the 2-1 quarter-final victory over Tunisia on Sunday and says he is getting to grips with the system.“It’s normal. This is my first big tournament so it would take time for me to get into the system and today [Tunisia match] was good," the Ghana goalkeeper said after the game at the Stade de Franceville."It was nice to get a good game again because I haven’t felt that I have been on top. Today, it felt good, something is coming back again, so it’s nice."He made his debut for the Black Stars in September last year in a Nations Cup qualifier against Swaziland and has gone on to make the number one jersey his own.The goalkeeper admits that he is a bit baffled with the criticisms leveled at him but accepts them in good faith.“It takes time but you just have to be bold and jump into it. Today, it was no nonsense and I just had to play well. It was good. I can’t accept certain things but it’s football," he said.And he believes the only way to answer his critics is to ensure that he continues to perform well for the Black Stars."You have to accept certain things. The only thing I can do is to answer them on the field and I think today, what I did for me is normal and I think I can do much, much better."
