Everton boss David Moyes admits Marouane Fellaini's future could depend on a top four finish.
Fellaini has been linked with Chelsea and Manchester United this season.
And Moyes admitted: "I would really hope Fellaini will stay if we were in the Champions League.
"Of course, he might still go for the money on offer somewhere else, but at least he wouldn't be going for the Champions League.
"If you want to keep your best players you need top European football because they want to be involved in that.
"I agree with Arsene Wenger that finishing in the top four is the equivalent of winning a trophy - even if you don't get to parade silverware.
"I don't know whether every financial problem would be solved just by qualifying.
"But, for me, it would have an absolutely massive impact in terms of keeping the players I have and bringing in new faces."
