Samuel Inkoom is expecting much more of a challenge from Sudan than Ghana faced in the reverse fixture in Kumasi back March of this year.Ghana, chasing a third consecutive appearance at the World Cup finals claimed a 4-0 home win against Sudan in the Group D qualifying of the 2014 FIFA World Cup.With three more matches to complete the second round stage of matches, Inkoom, who is making a return to the Black Stars after a long absence expects a tough test in Omdurman on Friday when Ghana plays Sudan."Every player wants to show something and prove to the coach that he is good. The most important thing is that we need to stay focused, listen to the coach and keep on working hard," Inkoom said at Ghana's training camp in Addis Ababa, Ethiopia."I believe this team. I have trust in my colleagues. It's not going to be easy. We have been there twice. But I believe that we are going to beat them."The Black Stars are just one point adrift leaders, Zambia on the log with the side that finishes top, advancing to the third round stage.For Inkoom and his colleagues despite a long and busy club campaign in their various leagues abroad, sacrificing to put smiles on the faces of Ghanaians means so much to them."Everybody knows we have a big game ahead of us which is against Sudan and Lesotho. We need to sacrifice for our nation as well. Our leagues are over and we need to come and see the family and it's not easy at all."It's our nation, we need to put everything aside. If the nation is happy, we are also happy. We need to sacrifice for our nation because football is different in every country. It brings a lot of people together so we need to sacrifice," the defender said.After the game with Sudan, the Black Stars travel to Johannesburg on 9th June and will train in the South African capital for four days before departing to Maseru for the match against Lesotho.
