Everton boss David Moyes admits their wages budget will have to increase.
Moyes made the re-signing of star players his top priority over the summer.
Tim Cahill, Jack Rodwell, Leighton Baines and Seamus Coleman all committed to new long-term deals.
Moyes feels he has a squad capable of competing with the best of the Premier League and is anxious to keep it together, but accepts money is an issue.
The Scot said: "We have the value on the field. We may not have it in the bank but we have it on the field.
"We have to make sure we keep the ones we have got, but wages will have to increase."
