Juventus coach Gigi del Neri says victory over Cagliari was routine thanks to having fit strikers in his starting XI.
Alessandro Matri and Luca Toni both struck in the 3-1 win at Cagliari.
"We always said that Juve paid the price for not having the right players in the right place, especially in the box," said Del Neri.
"Both Martinez and Milos Krasic did well interpreting their roles, but we changed to a 4-3-1-2 giving Alessandro Del Piero and Matri more freedom.
"Do not forget that at Palermo we only had Martinez as a reserve in attack and he's not really a forward. We should have Vincenzo Iaquinta back soon too, so it's easier when you actually have strikers...
"It's not simple to win at Cagliari, so this result gives us great confidence for the future, even if we have to keep our feet on the ground. We know we're on the right track."
