Snapshot | When the Swans toppled the holders
Nathan Dyer puts his finger to his lips after putting Swansea City in front at Portsmouth on a day when Roberto Martinez's team pulled off a famous FA Cup win.
Portsmouth, a Premier League team at the time, were the cup holders having beaten Cardiff in the 2008 final.
They included a host of star names against the Swans, including David James, Sol Campbell, Peter Crouch and Nwankwo Kanu.
Yet it was Martinez's Championship side - who had only been promoted from League One the previous spring - who claimed a deserved fourth-round victory at Fratton Park.
The victory was especially sweet for Dyer who, because he was on loan at Swansea from Southampton, was booed every time he touched the ball by the home crowd.
The winger was inspired by the stick he received, and deservedly put the Swans in front on 26 minutes when he latched on to a Jason Scotland through ball and beat James.
The visitors had to withstand some Pompey pressure, with keeper Dimi Konstantopolous having a fine game.
But the Swans put themselves in a commanding position just before the break when Nadir Belhadj fouled Jordi Gomez in the box.
Scotland stroked home the penalty, and Martinez's men defended manfully after the break to seal a memorable win.
