At the same time, the Werkself have loaned out Panagiotis Retsos to the Premier League club Sheffield United to the end of the season. The versatile defender Retsos has a contract at Bayer 04 to 30 June 2022.
"Edmond Tapsoba was a regular first choice at Guimaraes at the age of 20 and in addition to his defensive ability, he’s also dangerous in front of goal," said Bayer 04 sporting director Simon Rolfes in commenting on the signing of the 1.92 metre tall defender. Tapsoba has made 32 appearances for the Portuguese side this season, scoring eight goals including three in the Europa League. And sporting managing director Rudi Völler added: "His really big potential makes Edmond Tapsoba a very interesting proposition as a player. We are happy we've been able to complete this transfer."
The signing of Tapsoba enabled Retsos to go out on loan: "Panos has lost a whole year through injuries and it's important for him to play now. The Premier League club Sheffield United offer the highest level for him to get back to top form," said Völler.

“As far as mentality and determination are concerned, we have nothing to reproach ourselves for,” Robert Andrich said up after the first home defeat for the Werkself this term. In terms of their play, too, the Black and Reds put in a respectable performance for long stretches of this intense and physical match, outperforming VfB Stuttgart in most areas. It was only in terms of efficiency in front of goal that the Swabians had the edge over the Werkself. Head coach Carles Martínez wants to learn from this so that, in future, they can “win this sort of match too”. The Werkself review.
