Croatian striker Jelavic has caught the eye since joining the Toffees from Scottish side Rangers in January with 10 goals from 17 outings.
However, Jelavic is currently out of action with a leg injury, which has left Nigerian frontman Anichebe to fill void.
Having scored two goals in as many matches, Anichebe has confessed that he has benefited from working alongside Jelavic.
"I have been watching Nikica play and he is always in the middle of the goal," Anichebe told the club's official website. "He picks the right time to link up and that is something I want to do more – be in those positions to score."
Anichebe, 24, has spent his entire career at Goodison Park.
