Algeria coach Abdelhak Benchikha resigned Sunday after a 4-0 drubbing by Morocco in a high-profile Africa Cup of Nations qualifier.

Mehdi Benatia and Arsenal striker Marouane Chamakh scored during the first half in Marrakech and Youssouf Hadji and Oussama Assaidi struck within nine minutes after the break to complete an unexpectedly one-sided triumph.

It was sweet revenge for Morocco under Belgian coach Eric Gerets after a 1-0 away loss to their North African neighbours in the qualifying competition three months ago.
