Everton manager David Moyes has admitted he is having to give young players a chance sooner than expected as he re-shapes his team.
Striker Denis Stracqualursi and winger Royston Drenthe were the only signings, so teenagers Ross Barkley and Apostolos Vellios have been given their chance.
"I'm having to try to build a new side from what we've got," Moyes said.
"I need to get myself in the right position in the league but also I need to see where we can take it on and try to find the new (Tim) Cahills."
Barkley, 17, has already impressed in all four of the Toffees' matches so far, while 19-year-old Vellios made his first appearance of the season - and only the fourth of his Everton career - as a substitute in the 2-2 draw with Aston Villa.
Despite only being on the pitch for five minutes Vellios almost scored twice.
Moyes said: "If people hadn't seen the Greek boy (Vellios) who came on they'd say 'Boy oh boy, you're not the worst are you? You've done okay and were unlucky not to get one or two goals'. And we have another couple who are similar to that.
"The problem is if you are trying them out in the Premier League it's a risk and at the moment I'm risking them.
"Ideally you would go and get them Championship experience so they know what the speed is like and the game is like and what they have to do. But because of our numbers we have to use these boys either in the team or to fill out the bench."
