“I hope to try different systems (in these matches), so we can change when necessary,” Rohr said.

“We have played 4-3-3, 5-3-2 already.

“We also hope to improve team harmony after did well in last two games, while playing offensive football.”

Rohr has also disclosed he will give fresh call-ups Joel Obi (Torino), Junior Ajayi (Al Ahly) and Gabriel Okechukwu (Akwa United) a chance to stake a claim for places on the World Cup-bound squad.
