The 23-year-old joined the Swans from Liverpool two years ago and has gone on to become a firm favourite at the Liberty Stadium.

And he has been rewarded for his performances with Garry Monk’s team, with the new deal tying him to the South Wales outfit until July 2019.
Born in Essex, Shelvey started his career as a teenager with Charlton Athletic, where he quickly broke into the senior squad to become their youngest first-team player at just over 16 years old before catching the attention of Liverpool.
A switch to Anfield duly followed in 2010, as Shelvey continued to add to his international experience with England at U16s, U17s, U19s and Under-21s level.
He received his first England senior cap against San Marino in October 2012 and last featured in Roy Hodgson’s squad in October for the games with San Marino and Estonia.
