A superb team performance ensured the Black Stars of Ghana beat Sudan by four goals to nil in a World Cup qualifier played at the Baba Yara Sports Stadium in Kumasi.Asamoah Gyan opened the goal harvest with a tap-in early on in the first half with Wakaso getting the second later on in the half.Abdul Warris etched his name on the score sheet with a superb leap and a sumptuous header in the second half and provided the assist for Agyemang Badu later on in the second to end the Ghana rout against Sudan.After another botched Nations Cup tournament, the Stars had to win this match to boost their own confidence and to rally the supporters behind them.For Coach Akwasi Appiah this match meant so much for him and for his continued stay as coach of the Stars. He had to deliver. The thousands of fanatic supporters who had trooped to the Kumasi Stadium several hours before the match wanted him to and he did. The team did.Gyan and Waris combined well in attack for the Stars and within few minutes the Spartak Moscow striker forced a superb save from Maghoub El Muz in post for Sudan.Gyan however shot the Stars into the lead in the 18th minute with the easiest of tap-ins after he was set up by a header from John Boye.Mubarak Wakasu increased Ghana's tally in the 37th minute with a well taken shot just at the edge of the 18 yard box.The Espanyol attacker wrapped his foot around the ball to connect an immaculate cross on the right from Harrison Afful. The Stars could have been up by a wider margin but Gyan's set pieces were wayward.The Sudanese lacked ideas and hardly tested Fatau Dauda for most part of the first half.After recess Gyan was forced out of the game with a muscle strain and Agyeman Badu came in.Skipper Sulley Muntari was also subbed for Solomon Asante early in the second half but it was the Sudanese who appeared to have benefited from the changes.The Sudanese controlled the game but hardly created any goal scoring opportunity.Waris against the run of play teasingly outwitted his marker in the 18 yard box and was brought down for what appeared to be a legitimate penalty but the referee surprisingly had him booked for diving.In the 75th minute, the Spartak Moscow striker soared above his marker and headed home a cross for Ghana's third.Eight minutes later, Waris selflessly set up Agyemang Badu for the final goal.Sweet victory it was for the Stars, particularly for Waris who earned his first cap and his international goal.
