Striker Romelu Lukaku says he must find his killer instinct if he is to keep helping Everton move forward.
The Belgium international ended a drought of 11 Premier League games when he hit an 11-minute hat-trick against Sunderland at the Stadium of Light on Monday night.
Everton now sit third and remain just one of four teams still unbeaten during the opening four games of the Premier League campaign.
Lukaku has admitted he needs to maintain his form if the Merseyside outfit are to fulfil their ambitions for this season.
“I think we could have done better, especially in the first half,” Lukaku told Sky Sports after the Sunderland win.
“Up front we didn’t keep the ball and create enough. But the second half we performed way better and it was deserved win.
“It was all about my fitness levels, they weren’t as good as I wanted them to be. But in the Premier League you have to be focused until the end and I got got good service from Yannick [Bolasie] and Kevin [Mirallas] at the end, and managed to finish the chances.
“I think I could have had five really, I need to be more of a serial killer if I want to help the team achieve its objective.
“We are in a good position in the league and we have to keep going.”
