Gernot Rohr, Super Eagles manager reckons that the Flying Eagles lack of firepower in attack is their greatest weakness ahead of their semifinal showdown with Mali in the U20 Africa Cup of Nations.

Paul Aigbogun's sidehave shown great defensive solidity in their three matches so far at the ongoing tournament, having failed to concede against Burundi, South Africa and Niger.

Rohr has predicted that Nigeria will qualify for the U20 AFCON showpiece if they score first against the Malians because they are organized at the back.

"Now the semi-finals are decided after one game. We know it is a Cup game so these are special matches,'' Rohr told Foot Mali.

"It is important in this game to score the first goal and to have a good defense which Nigeria has.

"But Mali also made a good impression, so this match between Nigerians and Malians seems very open. Both teams have shown great things since the beginning of the tournament.

"I saw both play their last match in Niamey. Nigeria lacks a bit of offensive strength. And Mali has earned a deserved victory in its match against Ghana so we can just say that it's going to be a good match and very tight especially.”

The Flying Eagles will face off with Mali at the Stade Général Seyni Kountché, Niamey on Wednesday, starting from 1630 hours.
