Sergio Oliveira's 113th-minute free-kick shocked Juventus to send Porto through in a stunning Champions League round of 16 tie despite a 3-2 second-leg win for the Italian side.

Oliveira's long-range free-kick deep into the second half of extra-time went through the legs of Cristiano Ronaldo in the Juventus wall to make it 2-2 on the night and give Porto the lead over two legs. .

Adrien Rabiot's thumping header two minutes later gave Juventus hope, only for Porto goalkeeper Agustin Marchesin to produce a stunning save in the final moments to ensure the Portuguese champions advanced on away goals.

Porto had opened up a 3-1 aggregate lead through Oliveira's 19th-minute penalty after Merih Demiral brought down Porto's Mehdi Taremi.

But Juventus' Federico Chiesa found the far corner from a tight angle in the 49th minute before Taremi was shown a second yellow card for kicking the ball away.

And Chiesa headed in a Juan Cuadrado cross after 63 minutes to level the tie on aggregate.

It looked Juventus would capitalise on their man advantage but Porto defended superbly to take the match extra-time where Oliveira's decided the tie.
