Nigeria coach Rohr wants Arsenal forward Iwobi to score more

"Although only 23, Alex is an experienced international and I want to see him scoring more regularly for the national team," said German Rohr.

"He, Odion (Ighalo) and Ahmed (Musa) can cause a lot of damage to opposition defences if they click at this Cup of Nations."

Rohr has cause for concern as Nigeria failed to score in two warm-up matches against fellow qualifiers, drawing 0-0 at home to Zimbabwe and losing 1-0 to Senegal in Egypt.

But a favourable draw -- Guinea and Madagascar complete Group B -- should ensure Nigeria top the standings and book a last-16 place.

Here, AFP previews the three Saturday matches with Guinea playing Madagascar in the other Group B fixture and the Democratic Republic of Congo and Uganda squaring off in Group A.

Nigeria v Burundi

Nigeria are the fourth highest ranked team in Egypt and Burundi the lowest with 89 places separating them in the world rankings.

But Rohr became upset the second a reporter described this match in the coastal city of Alexandria as one the three-time champions should win comfortably.

"The national football association president (Amaju Pinnick) says we must win this tournament, but we have a very young side."

However, the coach can call on three of the 2013 Africa Cup-winning squad, captain John Obi Mikel, Kenneth Omeruo and Musa, to provide experience.

Ranked among the no-hopers, Burundi have impressed in preparatory matches against former champions, holding Algeria and losing in stoppage time to Tunisia.

Guinea v Madagascar

Both experienced Cup of Nations campaigners Guinea and newcomers Madagascar will aim to brush aside poor warm-up form and launch their campaign with maximum points in Alexandria.

Guinea lost to the Gambia, Benin and Egypt while Madagascar drew with Luxembourg after conceding two stoppage-time goals before failing against Kenya and Mauritania.

The Guineans hope Liverpool midfielder Naby Keita can play after injuring a thigh in the Champions League semi-final against Barcelona.

Keita and his team-mates can draw comfort from having Belgian Paul Put as their coach -- he took outsiders Burkina Faso to the 2013 final before losing narrowly against Nigeria.

Madagascar coach Nicolas Dupuis -- one of seven from France at the tournament -- has worked wonders to get the Indian Ocean island state to the finals, but further progress is unlikely.

DR Congo v Uganda

Democratic Republic of Congo captain and Celtic midfielder Youssouf Mulumbu has raised the bar considerably by saying his country can win the competition.

"Provided we can fix a few things, there is no reason why this team cannot go all the way," he said ahead of a Cairo clash with Uganda.

"We reached the semi-finals and the quarter-finals in the last two editions and I believe the team is better now under our great coach Florent (Ibenge)."

With Mohamed Salah-inspired hosts Egypt expected to win Group A, a tight contest is set to unfold between DR Congo, Uganda and Zimbabwe for second place, and a guaranteed last-16 slot.

Uganda coach Sebastien Desabre is less boastful than Mulumbu, saying: "We aim to achieve decent results, especially in our first match against the Congolese."
