Mainz have finalised the signing of Armindo Sieb from Bayern Munich, with the official announcement expected soon. The 20-year-old forward has agreed to a new contract with Bayern, extending his stay until 2027, before moving to Mainz on a two-year loan deal. The agreement includes an option for Mainz to purchase Sieb permanently, while Bayern retain a buy-back clause.
Sieb, who has been with Bayern since 2020, is known for his versatility in attack and has been a promising talent in the club’s youth setup. This move to Mainz is seen as an opportunity for him to gain more first-team experience in the Bundesliga.
