ROME (REUTERS) - Paulo Dybala scored twice against his former club as Juventus thumped Palermo 4-1 at home on Friday to move 10 points clear at the top of Serie A, with Claudio Marchisio and Gonzalo Higuain also finding the net for the reigning champions.

Juve coach Massimiliano Allegri called on his players to be "spectacular" in their hunt for a record sixth consecutive Scudetto title and they responded with a scintillating display to move up to 63 points after 25 matches.

Marchisio, feeling his way back into the side after injury, opened the scoring in the 13th minute to give Juve the lead their dominance merited.

Dybala fired an early free-kick against the post but made amends with a sensational goal from another free-kick five minutes before half-time.

The Argentine forward refused to celebrate against the club he spent three years with but showed no mercy in the 63rd minute when he picked out Higuain who finished calmly before completing the rout when he slammed home from the edge of the box.

Palermo's Ivaylo Chochev headed a consolation goal past Gianluigi Buffon in stoppage time but his effort could not dampen the mood as Juventus warmed up in style for Wednesday's Champions League last-16 first leg at Porto.

The victory made it six Serie A wins in a row for Juve, taking them 10 points clear of second-placed Roma ahead of their home game against Torino on Sunday.
