Majority owner Farhad Moshiri has already spent around £300m since he bought into the club in February 2016 but is currently on an austerity drive.
He refused to fund any new signings in January and now wants players sold and the wage bill trimmed to a more manageable level.
But captain Coleman says: “If we did get into Europe, I think that would change the plans for the manager and the owner. You might need a few more players because it is quite demanding.
“It would be massive. At the start of the season we knew breaking into the top six would be difficult but we wanted to get that seventh place.
"Everton should be in Europe every season. We've finally got the financial backing that maybe we've been missing for quite a period of time.
“That's where this club needs to be. It's the owner and the manager's decision but it would be great to hold on to the players we've got on loan.
“They've been great and their performances at certain points have been brilliant. If we were able to keep them that would be fantastic."
