Sporting CP have booked their place in the quarter-finals of the Europa League thanks to a 3-2 aggregate win over Viktoria Plzen, as Rodrigo Battaglia got the vital goal in extra-time in Thursday's 2-1 defeat.
The Portuguese side's luck appeared to have deserted them when Bas Dost saw a penalty saved in second-half stoppage time, sending the game to extra-time after Marek Bakos' brace had wiped out Sporting's 2-0 lead from the first leg.
But Jorge Jesus' men stepped things up a notch in the first half of extra-time, making the most of their superiority with Battaglia's header on the stroke of the interval, and Plzen - who needed another two goals in response - were left deflated.
It took the home side just six minutes to pull themselves back into the tie, as Bakos headed in at the far post following a fine Jan Kovarik cross from deep on the left flank.
However, Sporting did a good job of restricting their flow of further chances, and they should have drawn level just before the break - Bryan Ruiz slamming a left-footed volley wide from about eight yards out.
Sporting missed another glorious opportunity early in the second half.
Bruno Fernandes' long-range strike was parried to Marcos Acuna, whose follow-up effort bounced back off the right-hand post before he then hit the rebound over.
And Plzen capitalised just after the hour mark - Bakos sweeping into the bottom-right corner from just out the six-yard box following Radim Reznik's pinpoint cut-back.
Dost was presented with the perfect chance to get a vital away goal right at the end of normal time, but his tame penalty - which he had won - was easily saved by Plzen goalkeeper Ales Hruska, securing extra-time for the hosts.
Sporting's progression, though, was ultimately sealed just before half-time in extra-time, as Battaglia headed in Fernandes' cross, taking Sporting into the last eight.
