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.

Rüdiger Vollborn has been at the club for 40 years, he holds the record number of Bundesliga appearances for the club (401) and is the only Bayer 04 player to have won both the UEFA Cup (1988) and the DFB Pokal (1993). And the Berliner stayed with the Werkself after ending his impressive playing career working as a goalkeeping coach for the following nine years. Vollborn now works under the Bayer Cross as a fan liaison officer and club archivist. Since February 2021, the personal Black and Red lexicon takes Werkself fans under the heading of 'Rudi recounts...' on a brief trip through the history of Bayer 04 every month…

The BAYER 04 HILFT Day is celebrating an anniversary: for the tenth year running, a large number of employees of the Bundesliga club have been getting involved in a community project in Leverkusen and the surrounding area. Following the refurbishment of the city library last year, this time around some 70 staff members rolled up their sleeves to help out at the Bunker Youth Centre in Leverkusen-Wiesdorf. With the support of the Lebenshilfe workshops in Leverkusen and partner Coca-Cola, a rubber football pitch was laid, a Bayer 04-style lounge was created and other projects were carried out. Werkself players and coaching staff also gave their all.
