Enyimba captain, Chinedu Udoji has warned his teammates to be wary of their CAF Champions League opponent, Vital'0 of Burundi.
The Nigerian champions have struggled for form this season, winning one and losing two of their opening three games in the Nigeria Professional Football League.
They secured a narrow 2-1 aggregate win against Ugandan outfit, Vipers Sports Club in the preliminary round.
Udoji said they will need to be at their best to beat the Burundians after they were pushed hard in the previous round by Vipers.
"This game (against Vital'0) is an important one for us and we cannot afford to underrate them after what experienced against Vipers in the previous round," the former FC Abuja defender told Completesportsnigeria.com.
"To scale through this hurdle, we have to be at our best and I believe we have the quality to go far in the competition. But we have to be at our best and not get complacent along the way."
