Our no.8 first tee'd up Goncalo Ramos with a perfectly-weighted pass on 18 minutes, with former Red Cristiano Ronaldo doubling Selecao's advantage from the penalty spot just before the half-hour mark.
Slovakia then grabbed a goal back through David Hancko with twenty minutes to play, before our Portuguese playmaker turned provider once more, with his low cross tapped home by Ronaldo for his second of the evening.
Napoli's Stanislav Lobotka did grab another for Slovakia to make it 3-2 in Porto, but it was Roberto Martinez's side who booked their spot at next summer's tournament in Germany with victory.
