The Dervishes have the upper hand to go through to the group stage after grabbing a 1-0 away victory over Wydad.

However, Neveu is worried that his players may have an unserious approach to the match, given the first-leg result.

"We have to be cautious, the Moroccan team have nothing to lose so they will attack in order to overturn the first-leg deficit," the French tactician told FilGoal.com on Thursday.

On the other hand, Wydad boss Ladislas Lozano insisted his side are capable of beating Ismaili, adding that an early goal would mount pressure on the hosts.

"The first-leg result is not final. We can win in Egypt just like what they did in Morocco," he said.
