Andrea Pirlo has warned Juventus teammates not to relax.
Juve are ahead of second-placed AS Roma by seven points.
But Pirlo says: "A seven-point lead is nothing, Roma are strong and they will be a tough nut to crack.
"Udine is a tough place to go. They are emerging from a good result against Empoli that took them away from the danger zone in the standings, so they can play without tension.
"We, on the other hand, have to win, if we are to keep Roma at a distance."
