Lichtsteiner scored the second goal for Antonio Conte's men in the 2-1 win this afternoon.
The Switzerland international admitted that Juve struggled in the second half, but was happy to get the three points after their recent poor form.
"Today's victory was very important for us. We dropped many points in January, which was also down to an element of bad luck," the defender told Sky Sport Italia.
"We struggled a bit in the second half and could have handled things a little better after the restart.
"We're still top of the league, but we know we'll need to remain alert because Napoli are a great side, as are Lazio and Inter."
Juventus sit at the top of the table with a three-point lead over Napoli.
