Substitute Jackson Martínez struck twice at the death as FC Porto came from 2-0 down to claim a point at FC Shakhtar Donetsk in Group H.

The visitors' frustrating evening looked to be capped when Luiz Adriano doubled Shakhtar's advantage five minutes from time. Porto, though, refused to be beaten. They stormed forward and won their second penalty of the night when Yaroslav Rakitskiy handled. Martínez beat Andriy Pyatov and was then on hand in the fourth minute of added time to tap in at the near post and earn a remarkable draw.

The Arena Lviv was packed on its introduction to the UEFA Champions League and at times in the first half it seemed only the partisan crowd's collective will was keeping Porto at bay. Their attacking trio of Cristian Tello, Óliver Torres and Yacine Brahimi ran the home defence ragged, constantly pushing and probing at a high defensive line.

It made for a challenging opening period for Olexandr Kucher, only playing after passing a late fitness test, and ten minutes before the break it proved a step too far as Brahimi went down under his challenge. With memories of his matchday one hat-trick billowing wind in his sails, the forward appeared confident but Pyatov guessed right and was right.

The crowd breathed again but they always had cause for optimism. Shakhtar's Taison had tested fellow Brazilian Fabiano with an early swerving effort and Maicon so nearly scuffed in the most innocuous of own goals. Time and again the final ball was lacking, yet when they did find their poise seven minutes after half-time it came from a surprising source.

Centre-back Kucher found himself in an advanced position on the right and pounced on a moment of dalliance from the similarly misplaced Torres. A simple square ball across the box and Alex Teixeira did the rest. Kucher was quickly in more familiar surrounds, with the Ukrainian champions defending ever deeper as Porto pushed for the equaliser.

They came close too, but Pyatov simply returned to centre stage. His stop from Adrián López eight minutes from time looked to be decisive, especially when Shakhtar surged forward and Luiz Adriano tapped in to make it 2-0. Martínez, though, had other ideas.
