Everton are still in the hunt for a top four spot come the end of the season but they look more likely to make it into the less glamorous and less lucrative Europa League.
Baines, who is seen as one of the club's most valuable assets, says the lack of investment in the club is once again coming back to haunt them as their squad depth is nowhere near as strong as their rivals.
"We have been steady over the years. We have been shy of challenging for the Champions League places and are managing to edge our way closer," Baines said.
"We have not had that big push in terms of giving the manager that backing to go and buy the players who would really put us right in the mix.
"It is one thing having it and obviously you have to spend it wisely.
"You have to get the right players and those who fit, so it would not be a given if we were to get a good amount of money, but it would definitely help."
