Everton boss Dave Moyes admits fans cannot expect Yakubu Aiyegbeni to run all day.
"We wanted a player who would get on the end of passes and score goals to elevate us up the table - and that's three he's scored in the Premier League now and another one in the cup, so he's beginning to do what we wanted.
"Goals was always the priority, but of course we want hard work as well. Yak is different to Andy Johnson and James Vaughan, but he's buying into the work ethic.
"Some players come into a new club and settle straightaway, but it does take others a little time and Yak is starting to find his feet now."
