Ghana coach Ratomir Dujkovic said that his team have a tough task in their hand ahead of their decisive game against the USA on Thursday. Ghana will meet USA in the final group E clash and the Black Stars have the chance of reaching the second stage if they won the game. The African debutants can also advance if they grabbed a point should Italy beat the Czech Republic. "The USA are very strong and even though they'll have two players missing through suspension, they have excellent replacements," Dujkovic told FIFAworldcup.com. "It will be a very difficult game as we also will be without Asamoah Gyan and Sulley Muntari due to suspension." The Serbian coach is leading Ghana in their first ever World Cup and despite the lack of experience, Dujkovic is confident of his players' abilities. "This is the pinnacle of my career, I believe Ghana can go all the way to the semi-finals, though that depends of course on the USA game," Dujkovic said. "I think this is Ghana's time now, the country waited a long time to be in the World Cup, now we are here and I believe we can go excellent run."
