Trailing 2-1 from the first leg, the Italian giants were still expected to overturn the deficit back on home soil. Their task, however, was rendered even more difficult when Sergio Oliveira put the underdogs further ahead from the penalty spot in the 19th minute.
To their credit, Juventus fought back and managed to force extra-time thanks to two second half goals from Frederico Chiesa, but their fate was ultimately sealed by Oliveira’s free-kick with five minutes remaining.
Adrien Rabiot who, along with Ronaldo, turned his back on Oliveira’s strike, levelled the tie on aggregate two minutes later, but Porto progressed on the away goals rule.
Afterwards, former Juventus coach Capello lamented the lack of bravery demonstarted by Ronaldo and Rabiot and also questioned the senior players in Pirlo’s squad who refused to front up to the media following such a disappointing result.
He said: ‘That was an unforgivable error,’ Capello told Sky Sport Italia pundit. In my day, you chose the players who went into the wall and they couldn’t be someone afraid of the ball.
‘They were scared of the ball and jumped away from it, turning their backs. That’s unforgivable.
‘You see only the youngest players actually stepped in and showed their face during the tough moments. In this team, there are some veterans who turn up when they win to take the credit, then are nowhere to be seen when they lose.’
‘It had never happened before that they’d turn around, maybe they felt it was so far out that they didn’t sense the dange.
‘It was a mistake, it usually doesn’t happen, the players didn’t feel it was a dangerous situation and conceded a goal.’
