Swansea City have become the first Welsh club to win a major English trophy since 1927.
The Swans completely dominated the Capital One Cup final against League Two side Bradford City, who had to play the last half an hour at Wembley with 10 men and lost the contest 5-0.
Nathan Dyer gave the Premier League outfit a deserved lead on 16 minutes, when he tapped home from close range, after goalkeeper Matt Duke had failed to hold Michu's low effort from the edge of the area.
Michu made it 2-0 with his 19th goal of the season five minutes before the break.
The Spaniard collected Pablo Hernandez's clever pass, before turning Carl McHugh and poking the ball into the corner of the net from 16 yards.
Dyer doubled his tally early in the second half.
The former Southampton winger played a neat one-two with Wayne Routledge before producing a crisp left-foot finish that gave Duke no chance.
Duke was dismissed just before the hour mark for a clumsy foul on Jonathan de Guzman inside the penalty area.
De Guzman and Dyer, who was on the verge becoming the first ever player to score a hat-trick in a League Cup final, then squabbled over who should take the spot kick.
The Dutch international won the argument and converted with expert precision.
De Guzman scored again in stoppage time to make it 5-0, which set a new record for the biggest margin of victory in a League Cup final.
Swansea will compete in the Europa League next season.
