SuperSport United coach Pitso Mosimane admits he knows absolutely nothing about Confederation Cup opponents Dolphin Football Club.
Matsatsantsa travel up north to take on the Nigerians in a fourth round, first-leg clash on Sunday at the Liberation Stadium.
However, Mosimane concedes that their preparations have been hampered by the fact that they don't know too much about the opposition.
"We don't know much about Dolphin, except the fact that they participated in the Champions League and failed to qualify for group stage. They are a closed book to us," he told the club's official website.
"They are a closed book to us. We actually have to win this one and not concede to avoid pressure in the return visit. It is obviously going to be tough, as we will be playing away.
"They will be having their supporters cheering them all the way, and using their home ground advantage as well. But looking at the current performance of our squad, we promise our supporters positive result."
