Sweden upset the odds to beat Portugal 4-3 on penalties after the final of the UEFA European Under-21 Championship ended goalless.
The sides shared a 1-1 draw when they met in the group stage six days ago and there was nothing to separate them once more at Prague's Eden Arena.
But Rui Jorge watched his team's early verve fade and John Guidetti went close to snatching victory for Sweden within 90 minutes.
Extra time also failed to produce a winner, leaving AIK goalkeeper Patrik Carlgren to take centre stage.
He sprung to his left and kept out Portugal's third kick from Ricardo Esgaio and, after Sweden midfielder Abdul Khalili paid for an ill-advised staggered run-up, highly touted Sporting Lisbon midfielder William Carvalho saw his tame attempt thwarted by Carlgren.
Midway through the half Sweden appeared to have settled and Oscar Lewicki hit a drive at Sa as Portugal's attacking threat subsided.
Their earlier incision returned seven minutes before the interval but Mario's tamely struck shot was blocked by defender Alexander Milosevic.
The Scandinavians looked to attack more frequently after the interval but they were vulnerable on the counter after 52 minutes when Bernardo Silva’s dangerous low cross was scrambled behind.
A minute later, Guidetti - who had been starved of service in attack for Sweden - smashed narrowly over on the end of Thelin’s knockdown.
Back came Portugal as Oliveira crashed a 30-yard strike wide - the skipper's last act before making way for Toze.
The new man from Porto forced Carlgren to grasp a viciously dipping strike at the second attempt before fellow substitute Iuri Medeiros arched a shot just wide of the far post following a trademark driving run from Carvalho.
Hakan Ericson's team took their renewed belief into the additional period - Khalili curling a delicate effort wide to worry an increasingly jaded Portugal, who were briefly roused when substitute Goncalo Paciencia flashed a header past the post.
Paciencia tucked away Portugal's first penalty of the shootout with aplomb but it was their fifth and final effort from Carvalho that was cruelly decisive, as Sweden sealed their maiden crown.
