Ayew joined the Swans on transfer-deadline day in January 2017 as part of a swap deal which saw Neil Taylor move to Aston Villa.
Jordan, the younger brother of former Swan Andre Ayew, penned a three-and-a-half-year deal at the Liberty.
Ayew arrived in English football in the summer of 2015, when he joined Villa from French club Lorient.
His first season in the Premier League saw him score seven goals in 30 top-flight appearances – making him his club’s top scorer – but there was huge disappointment as Villa were relegated to the Championship.
Ayew started his senior career with Marseille, where he won the Ligue 1 title and three successive French League Cups.
He made an instant impression by scoring on his debut, and went on to score 15 goals in 126 appearances for Marseille during his five-year spell with the club.
A short spell on loan at fellow Ligue 1 side Sochaux saw his stock rise with five goals in 17 games, and that prompted a permanent move to Lorient.
His form at Lorient – he scored 13 times in 33 Ligue 1 appearances – caught the attention of Villa.
After relegation, Ayew spent half a season playing second-tier football for the Midlanders before securing a move to the Swans.
Ayew is a Ghana regular. He helped his national side to the Africa Cup of Nations final in 2015 and featured in their World Cup campaign in Brazil the previous year.
