Morata finished off a counter-attack and then converted a penalty in a three-minute span of the second half.

Joaquin Correa had put Lazio ahead early before Adrien Rabiot equalised for Juventus before the break.

The Turin side are third, seven points behind leaders Inter Milan, while Lazio are seventh.

Correa was ruthless when a bad pass from Dejan Kulusevski sent him away to stun Wojciech Szczesny on 14 minutes.

Juventus' Polish keeper had then to save drives from Sergej Milinkovic-Savic and Luis Alberto.

The first chance for the Bianconeri went begging when Morata, who started as single striker with Cristiano Ronaldo given a rest, nodded wide.

Rabiot left Pepe Reina standing when he cannoned his drive under the bar on 39.

The Spanish veteran keeper denied Federico Chiesa after the break and Milinkovic-Savic saw his header come off the bar before Morata completed the comeback by finishing a counter-attack triggered by Chiesa.

Milinkovic-Savic's foul on Aaron Ramsey led to a penalty that Morata fired past his compatriot Reina on the hour before giving way to Ronaldo.

"Today we played a great game after conceding, which was our mistake and it can happen," Chiesa said.

"We showed to have heart and grit, and from now onward we will fight as hard as we can."

Udinese beat Sassuolo 2-0 with Fernando Llorente and Roberto Pereyra striking to push the Udine side within four points of their ninth-place guests.

Llorente deftly turned in a deep feed from Nahuel Molina and after the break saw his skipper Rodrigo De Paul hit the top left junction before setting up Pereyra in stoppage time.

Spain veteran Llorente netted his first goal for Udinese since his late January transfer from Napoli.

Spezia and visitors Benevento opened the weekend with a 1-1 draw in a newcomers' clash and both moved six points clear of the drop zone.
