Juventus were condemned to a humiliating Champions League exit by a 4-3 loss at Benfica on Wednesday, as Rafa Silva's brace helped the outstanding hosts seal their own place in the last 16. 

Massimiliano Allegri's team arrived at the Estadio da Luz requiring a win to stay in contention in Group C, but were distinctly second-best after Dusan Vlahovic cancelled out Antonio Silva's opener. 

Benfica stormed into a 3-1 lead by the halfway mark as Rafa added to Joao Mario's penalty with a glorious backheel, and the winger doubled up with another wonderful goal after the break. 

Late efforts from Arkadiusz Milik and Weston McKennie ensured a grandstand finish, but it was too little, too late for Juventus as Roger Schmidt's men held firm.

It came as no surprise when Juventus fell behind after starting slowly, as the 18-year-old Silva met Enzo Fernandes' inviting cross with a glancing header to beat Wojciech Szczesny after 17 minutes.

The visitors levelled against the run of play when a VAR review overturned an offside call against Vlahovic four minutes later, but there was to be no such reprieve when Juan Cuadrado clumsily handled in his own area with 28 minutes gone.

Joao Mario picked out the top-left corner from the spot to re-establish Benfica's lead, then turned provider to tee up Rafa's flicked finish seven minutes later as the hosts threatened to run riot.

Rafa needed just five minutes to double his tally after the restart, dinking another cultured finish beyond Szczesny after latching onto Alejandro Grimaldo's throughball.

Juventus then gave themselves hope with a quickfire double; first with Milik volleying home Samuel Iling-Junior's cross before McKennie converted following a goalmouth scramble with 11 minutes remaining.

However, Benfica missed the best chance of an end-to-end finish when Rafa crashed a shot against the post, leaving the hosts to celebrate a famous win.

Cristiano Ronaldo's Portugal team-mate Rafa Silva has retired from international football having made 25 appearances for his country.

Benfica forward Silva was part of the squads that won Euro 2016 and the 2018-19 Nations League, while he was also called up for the 2014 World Cup and Euro 2020.

An impressive start to the club season, in which he has scored four goals in seven league matches, earned him a call-up for Portugal's upcoming Nations League fixtures against Czech Republic and Spain.

But the 29-year-old has instead retired from international football, stating he was calling it quits for "personal reasons" and describing it as an "honest and right decision".

Silva went on to say: "The national team will continue to bring joy to the Portuguese, from the very beginning in the League of Nations and the 2022 World Cup."

The Portuguese Football Federation added: "The FPF Board respects the decision taken by Rafa, who with us lived the two biggest achievements of the national team, Euro 2016 and the League of Nations.

"Rafa will forever be one of ours and he deserves our recognition and thanks."
