Ahead of Friday’s draw, we assess the credentials of the eight remaining quarter-finalists.
The rank outsiders left in the competition, and deep down the team everyone else is hoping to face. Showed great character against Roma to eventually overturn a 2-0 deficit, and stormed through their – admittedly quite gentle – group. Yet to be tested this season against one of Europe’s best sides.
Manager: Sergio Conceicao – one of Europe’s most respected young managers, who after ending Porto’s Primeira Liga drought last season has masterminded progress in Europe. 7/10
Star man: Alex Telles – a Brazilian left-back in the Marcelo mould, much of Porto’s best attacking play goes through the marauding defender. 6/10
Recent European experience: Reached the quarters four years ago, and going a bit further back won the Champions League in 2004. Also picked up the Europa League under Andre Villas-Boas eight years ago. 6/10
Form/momentum: A loss to rivals for the title Benfica was a major blow, but one that was quickly offset by defeating Roma to keep their European hopes alive. 7/10
Conviction: Reaching this stage is an achievement in itself but threat remains the threat of being overawed against one of the big boys – especially following last season’s home 5-0 thrashing by Liverpool. 6/10
