(CNN) -- AC Milan bounced back from the disappointment of missing out on a domestic double by beating Cagliari 4-1 on Saturday, with Robinho scoring twice.
Milan wrapped up the Serie A title last weekend but were denied a place in the Coppa Italia final following a 2-1 defeat by Palermo in the second leg of the semi on Tuesday.
However, Massimiliano Allegri's team scored three goals in the first 35 minutes -- two of them going to Brazilian forward Robinho -- to subdue the visiting Sardinians.
Robinho took his Serie A tally to 14 this season, joining compatriot Alexandre Pato and Zlatan Ibrahimovic as the club's top scorers.
