AC Milan coach Massimiliano Allegri heaped praise on Kaka after the Brazilian forward's impressive display on his return from injury contributed to a spirited 1-1 draw at home to Barcelona on Tuesday.

Injury-riddled Milan opened the scoring in the ninth minute when Robinho pounced on a defensive error to hold off Gerard Pique and beat Victor Valdes in the visitor's goal after a nice one-two with Kaka.

Lionel Messi knotted the score in the 23rd minute and despite being a thorn in the side of the Milan defense throughout, the Rossoneri weathered the storm at a packed San Siro to secure a precious share of the spoils.
