AC Milan director Barbara Berlusconi says finishing in the top three is crucial to their planning.
Milan are sitting in third place, a point ahead of Fiorentina.
"In this season of profound change, (coach Max) Allegri has overcome many difficulties and has worked well with the youngsters, who are our future," the daughter of President Silvio Berlusconi told Milan Channel.
"It is not up to me to make evaluations of the Coach, but failing to finish third this season would leave a bitter taste in the mouth.
"We are all fighting for a fundamental objective and that is the Champions League. We are all united!"
