16. Swansea City – Angel Rangel
Debut: August 2007
But for half a season spent at Sheffield United after leaving Swansea in 2010, Leon Britton would be the Welsh club’s longest serving player by some distance after first arriving, initially on loan, in the basement division of the Football League back in 2002.
As it is, however, the player in the Swansea squad with the longest unbroken run of being registered to the club is left-back Angel Rangel after he joined from Terrassa in 2007.
