The Portuguese international struggled at the Liberty Stadium.
In the summer Swansea City wanted to address their striking issues. The player they eventually brought into the club was the most inspired of signatures.
The forward had a good scoring record with the club but his record at international level had some Swansea fans worried and rightly so. He struggled to have any real impact on the first-team at Swansea after his move to the club.
In his 17 appearances with the club Eder managed to score a grand total of zero goals and was surely one of the worst summer signings in the Premier League.
In the end Swansea decided to move him on.
After signing Alberto Paloschi from Chievo the club sent Eder out on loan to Lille.
He has not taken long to make an impact for his new club.
He made his debut as a half-time substitute v Caen in midweek but this weekend he got the nod to start against Rennes.
He only went and scored. He netted the opening goal of the game in the first-half as Lille ended up drawing the game 1-1 - celebrating the game by oddly putting on a white glove.
Unfortunately he did not finish the game. Eder came off at half time after suffering a knee injury.
Swansea fans will be wondering where the goalscoring Eder was during his woeful spell at the Liberty Stadium.
