The African Cup of Nations is noted for the surprises it churns out year after year.Senegal, with its star-studded side, will head home from Group A in the 2012 competition after just two games. The Teranga Lions lost 2-1 to Zambia and they got a similar result on Wednesday against co-host, Equatorial Guinea.Such is the uncertainty that surrounds Africa's flagship competition.However, Ghana's Sulley Muntari is not entertaining the idea of a setback following Senegal's first round elimination masterminded by the debutants."I don’t want to even think about it [defeat]. Muntari said. "I don’t want to imagine it."For the Ghana attacker, winning every game remains his sole priority in the competition."All I want is to win and to be able to win the trophy because it is very important for us."It’s about time that we did something great for our nation, our people and for ourselves."Though determined to win in every game, Muntari anticipates some tough games ahead."It’s hard and it’s going to be hard but we would try our best," he said.
