AC Milan vice-president Adriano Galliani admits Ronaldinho is no first-choice starter.
The former World Player of the Year has struggled to make an impact since the turn of the year.
Galliani said: "At the beginning of the season we started with two lines of attack, the first is the trio - Kaka, Pato and Pippo Inzaghi, Ronaldinho for the second with Marco Borriello and Sheva (Andriy Shevchenko)."
