David Raya was the hero, saving two spot-kicks as Arsenal beat Porto 4-2 on penalties to progress to the Champions League quarter-finals after their last-16 tie ended 1-1 on aggregate.
Leandro Trossard, in for the injured Gabriel Martinelli on the left-hand side of Arsenal's attack, levelled the tie up after the scoring four minutes before half-time with a low finish into the far corner after being found by Martin Odegaard's delicious, disguised pass.
However, after Odegaard saw an effort controversially ruled out by referee Clement Turpin midway through the second half, the game went into extra-time and then to penalties.
And it was Raya who proved the home side's match winner after saving two Porto penalties, while the hosts were perfect from the spot to advance to the last eight of Europe's premier club competition for the first time since 2010.
