"We're in December and it would never be foolish to speak about our league aims," said the 40-year-old, who has confirmed that defender Leighton Baines is likely to return from a fractured toe against Sunderland on Thursday.
"We are trying to be very, very consistent. One defeat in 17 is a real consistent way of performing and the next step is to carry on developing and performing.
"I don't think we have reached our full potent yet and that excites me.
"We want to get to April with biggest amount of points we can, then we can set targets.
"One defeat in the league shows it has been a promising start. We have been getting the squad looking to do things in a more open-minded way, trying things, being brave.
"All it is a good platform for a strong second half, we don't assess it halfway through."
Everton face Sunderland and Southampton at home in their final two matches of 2013 before travelling to Stoke City on New Year's Day.
