Alexandria-Murad Teyeb: Tunisia defender Karim Haggui asked for humility ahead of his team's African Cup of Nations quarterfinal against Nigeria on Saturday. “We have to prepare well for our upcoming match in order to continue our African campaign successfully,” Haggui told Filgoal.com on Thursday. Haggui said he hopes his side had “learnt their lesson” following their stunning 3-0 defeat to Guinea in the conclusion of Group C matches which set-up a final eight encounter with the strong Nigerian team. “We have to put the defeat from Guinea behind our backs,” Tunisia striker Zied Jaziri said. “We'll have to keep working with the same enthusiasm and sincerity especially that we have a crucial quarter-final game ahead of us,” he added. The Troyes player exuded confidence as he said that the Tunisian team was not afraid of facing any opponent. “The Tunisian team is determined to have a successful African campaign that proves their continental supremacy,” said Jaziri. The Tunisian team held their final training session in Alexandria on Wednesday before traveling to Port Said to face Nigeria on Saturday.
