ROME, Nov 7 (Reuters) - Mauro Camoranesi struck twice in two minutes to set second-placed Juventus on their way to a thrilling 5-2 win at Serie A strugglers Atalanta on Saturday.

The Italy midfielder glided between the back line to head his side ahead in the 36th minute and then thumped in a loose ball for his third goal in two games after scoring in Tuesday's 1-0 victory at Maccabi Haifa in the Champions League.

Jaime Valdes pulled one back after the break for the Bergamo side trained by Antonio Conte, a contender for the job in Turin in the close season before his old Juve team mate Ciro Ferrara was promoted from caretaker to permanent coach.

Brazil midfielder Felipe Melo restored the visitors' cushion with a piledriver into the corner from well outside the box.

Atalanta's Fabio Ceravolo exposed the defensive fragility behind Juve's recent inconsistency in Serie A in the 71st, stepping inside his marker before curling the ball inside the far post.
