Sudan coach, Kwesi Appiah has advised Super Eagles head coach, Eric Chelle to do some polishing in his attacking line.
He spoke after the home-based Nigeria national team suffered a devastating 4-0 defeat at the ongoing African Nations Championship, CHAN, encounter on Tuesday.
Appiah watched as Sudan thrashed the Super Eagles B team to send Nigeria out from the competition.
Abdel Raouf's brace and a goal each from Walieldin Khedr and Leonard Ngenge (OG) gave Sudan the win against Nigeria.
The outcome of the encounter means Sudan now top Group D with four points from two games, while Nigeria have no point.
Speaking to the media after the game, Appiah said: "The coach only needs to do some polishing with the attack.
"The first game against Senegal was not that bad; in the second game, they had stints of possession, but our approach helped us.”
Sudan's next CHAN game is against Senegal, who defeated Nigeria 1-0.
