Raja Casablanca are provisionally through to the group stage of the CAF Confederation Cup after a goalless first half against El-Kanemi Warriors in the second leg of their second preliminary-round tie.
The sides remain level at 0-0 at the break at the Complexe Sportif Mohammed V in Casablanca, with the Moroccan club benefiting from the away-goals rule following a 2-2 draw in the first leg in Nigeria.
El-Kanemi Warriors have defended in a compact and disciplined shape, making it difficult for Raja Casablanca to find a way through.
The hosts have controlled possession for much of the opening half but have lacked the necessary sharpness in the final third to break the deadlock.
Despite their provisional qualification, Raja Casablanca will need to be more incisive after the interval if they are to avoid a tense finish at the Complexe Sportif Mohammed V.
