Juventus striker Mirko Vucinic says they cannot get carried away with their flying start to the season.
Vucinic started his first Juventus game at the weekend and set up Alessandro Matri for the only goal in an otherwise comfortable 1-0 win at Siena.
"Juventus has always been great. We've won two matches but we must keep our feet on the ground and continue our work.
"Being ahead in the table is important, but we mustn't forget that just one defeat would thwart our efforts, therefore we must be focused in every game.
"It doesn't matter how you start, the end is fundamental we're at the very beginning, and aware of our value.
"However, we must prove it every Sunday. We're doing so, because great sides must know how to suffer, and today [Sunday] we've done it, winning an important game."
