Influential Black Stars midfielder Mubarak Wakaso has revealed Comoros played an extra defensive game in Moroni but assured they were going to do everything to win in Kumasi.

"It was an extra defensive game from Comoros and it's always difficult no matter who you are when a team sets up that way," The Las Palmas man said.

"We will have to dig deep to ensure that we are able to go pass them, and we will do that in the second leg."

The Black Stars were lucky to escape with a 0-0 draw game in the first leg after what looked like a legitimate goal from tv replay was called offside to the disappointment of the thousands that had gathered to witness history in Moroni.
