Juventus boss Massimiliano Allegri was delighted with their 3-1 win over Cagliari.

Carlos Tevez, Fernando Llorente and Arturo Vidal struck for Juve.

"I was astonished by the change of system and did not expect it," Allegri told Sky Sport Italia after Cagliari coach Zdenek Zeman scrapped his trademark 4-3-3 for a 4-4-2 system.

"Considering the difficult moment they are going through and the fact they were up against Juventus, Zeman tried to close up the spaces and go on the counter. We did well to avoid running into difficulties.

"I was angry towards the end because in modern football a game isn't over until it's over, especially against a Cagliari side that never gives up, so we should've controlled the situation better when 2-0 and 3-0 up.

"After their goal we started playing again, but we shouldn't run risks like that. It was important to end 2014 on top of the table so that we can prepare at our best for the Super Cup."
