EVERTON manager Roberto Martinez expects to see much more from on-loan striker Romelu Lukaku after he struck twice on his home debut in the 3-2 win over Newcastle.
The Belgium international scored either side of Ross Barkley's maiden Goodison goal.
Despite a thunderbolt from Yohan Cabaye and a late prod from Loic Remy, the Toffees maintained the top flight's only unbeaten record.
Man-of-the-match Lukaku took the plaudits and Martinez admits he is pleased the terms of the striker's loan agreement ensures he cannot be recalled early by parent club Chelsea.
"I could be sweating now if that was the case," said the Spaniard, whose side moved above the Stamford Bridge club into fourth.
"Romelu is a young man who is still developing and he needs to go out on loan like he did last season.
"The next step now is taking what he did last campaign, in terms of number of starts, to another level.
"I don't think anyone questions the quality of Romelu otherwise they would never spend the money they spent at such a young age.
"We are only glad we can have him. The chemistry with the fans was terrific."
Asked if he thought Chelsea had made a mistake letting him join another club he added: "It will be easy to say that but you need to remember how many strikers they have.
"You need to mention Samuel Eto'o's record, Demba Ba's record and Fernando Torres' pedigree, you are talking about a squad which has phenomenal talent up front."
Newcastle boss Alan Pardew was less than impressed by his side's performance. "It would have been fortuitous for us if we'd got something from the game," he said.
