The central midfielder will play for the Bayer 04 U19 team. 16-year-old Sertdemir, who is of Turkish descent, is set to start with the first team squad in the pre-season under the new Leverkusen head coach Gerardo Seoane. The Swiss coach will meet up with his players for the first time on 5 July in Leverkusen.
“Zidan Sertdemir has a special talent. His signing is a great success for our scouting department after having had him on their radar for three years,” reported Bayer 04 sporting director Simon Rolfes. “We see great potential in Zidan and believe he will make the grade in professional football. That’s why we are including him in training with the first team straight away. Zidan should get experience with the senior squad early on and then take his time in moving up to the next level.”
Bayer 04 Leverkusen have extended midfielder Noah Mbamba’s contract by twelve months and sent the Belgian U21 international on loan to France. At FC Lorient, the 21-year-old – whose contract at Leverkusen now runs to 30 June 2029 – is set to gain playing time in Ligue 1 and, through strong performances and further development, put himself in the running for a future place in the Werkself squad.
