The Rossoneri were eliminated from Europe's premier club competition on Tuesday after a 4-0 defeat at Barcelona saw them bow out 4-2 on aggregate.
Nonetheless, Zapata believes the best way they can recover from the blow is by finishing in the top three of the Serie A this season and qualify once again for the 2013/14 campaign, starting with Sunday's clash against Palermo.
"We need to achieve our goal which is to finish second," he told Milan Channel.
"Palermo will be tough but we cannot fail."
Milan are currently third on the table but will be looking to overtake Napoli in second place in order to seal one of two guaranteed spots for next season's Champions League.
