Former Asante Kotoko captain Amos Frimpong says the Reds lost concentration in their 3-0 defeat against Etoile du Sahel in the CAF Champions League second leg tie in Tunisia.

The Porcupine Warriors failed to progress to the group stage of the Champions League after losing 2-3 on aggregates to the Tunisian giants despite a two-goal lead in the first leg.

Kotoko have been relegated to the CAF Confederation Cup where they reached the group stages last season.

Speaking in an interview with the Graphic Sports Online, Frimpong, who currently plays for Guinean side AS Kaloum, revealed that the second and third goals by the Tunisians could have been avoided if Kotoko have been alert.

“Playing against these North Africans are always difficult but I think at a certain point of the game I realised the team slept for some seconds and we conceded the second and third goal," he said.

“I felt the team did their best but it wasn’t enough and I expect them to come back stronger in the Confederation Cup upon their return to action,” he said.
