Juventus coach Alberto Zaccheroni doesn't believe Inter Milan will collapse in their title bid, despite their defeat to Catania.

Inter were shocked 3-1 in Sicily on Friday night.

Zac said: "The side that comes from behind always has more enthusiasm, the kind that comes from people thinking you were done for. In 1999 Lazio thought they'd already secured the Scudetto, but my Milan made sure we were ready.

"I don't know if this Inter will drop the ball as easily. They seem a tough side and I'm not sure what their problem is at the moment."
