Everton manager David Moyes believes new striker Yakubu Aiyegbeni will justify his £11.25m fee.
"You would not expect to get a striker with his record for the price that we have paid and hopefully that will look good business if he keeps going the way he has been," he told the club's official website.
"In today's market, it is a massive price for some other people, but we have never really been big spenders. What we have tried to do is improve the squad whenever the right players have become available.
"We might have relied a bit too much on AJ (Andy Johnson) and Tim Cahill at different times and we hope he can take some of the pressure off them."
And Yakubu is hoping to break the 20-goal barrier this season at Goodison Park.
"For the past four or five years I have scored between 16 and 19 goals," he said.
"This is the season I need to score more than 20 goals. I am looking forward to it and it is a big challenge.
"I'll have to work hard, but you have to believe in yourself."
