Swansea have defeated Reading 4-2 at Wembley to land the final place in next season's Premier League.
The Swans ended their 28-year drought from the elite, becoming the first ever Welsh team to make the modern day Premiership.
Scott Sinclair ended Reading's hopes in the 80th minute, however, completing his hattrick from another penalty.
Swansea join previously-confirmed QPR and Norwich in the top flight next season. West Ham, Blackpool and Birmingham make the reverse trip to the Championship.
