Everton goalkeeper Tim Howard has urged the Blues' board to splash out if they are to continue their progress under David Moyes.
The Toffees have backed manager Moyes in recent seasons and the Scottish boss has repaid their faith by steering the club to three top-six finishes in the last four years.
But Howard, who is preparing to make his 28th international appearance for USA against England on Wednesday, believes Everton must continue to invest if they are to break back into the top four and enjoy another taste of UEFA Champions League football.
"Nobody wants to be the one to say it but I will - the way football is at the moment you need money," he said.
"We have had a generous chairman who has given us money. Andy Johnson broke the record, Yakubu broke the record and we have to keep doing that if we are to stay up with the teams that are spending that money.
"It's a sad truth that nobody wants to say but if you look around the world, the teams who are at the top aren't the poor ones. We have a good team and a good squad so if we keep building on that we will have quality.
"If we have more depth we will be all right - we can challenge. We finished fifth this year so fourth is the next logical step."
