“I am not going to tell you what Ghana did wrong that made us get a point here because we have a game on Tuesday," Migne told said.
"All I can say is that the Ghana team is good and rich with many good players.
"My players played to my instructions and I felt that we should have won the game looking at the way we dominated the first half.
“But in the second half Ghana came back stronger and gave it their all and managed to get a goal and a point.
"We have seen how they play and we are going back to prepare for them on Tuesday.
“Hopefully we will get our first win of the qualifiers on Tuesday against Ghana.”
