Fer joined the Swans on a permanent basis in July 2016 following a successful loan from Queens Park Rangers.
Fer clocked up 11 appearances during his temporary stint with the Swans, making his debut against Tottenham before a first league start came in a memorable 2-1 win at Arsenal.
His performances were enough to convince the Swans to make Fer a permanent member of the squad, with the midfielder becoming the club's first summer signing.
He clocked up another 37 appearances in 2016-17, scoring a healthy six goals along the way to help the Swans dodge the drop to the Championship.
Fer began his career in the academy at Feyenoord, and made more than 100 appearances for the club after being handed his debut at the age of 17.
During his time at De Kuip Stadium, he featured in the Uefa Cup and helped Feyenoord win the 2008 Dutch Cup.
After winning plaudits for his box-to-box displays and technical ability, Fer moved to FC Twente in 2011, then joined Norwich City in August 2013.
He impressed for the Canaries, scoring four goals in 32 games despite the club being relegated to the Championship at the end of the 2013-14 season.
He then moved to Queens Park Rangers in August 2014, making 31 appearances and scoring six goals – including an impressive 25-yard strike against the Swans in a 1-1 draw at Loftus Road.
Despite Fer’s efforts, Rangers were relegated to the Championship at the end of the season.
After half a season in the second tier, Fer made the move to Wales.
He won the first of his Holland caps in 2010 and was part of the squad for the 2014 World Cup in Brazil, scoring against Chile in the group stage.
