Bundesliga club Holstein Kiel have been forced to defend their signing of USMNT international John Tolkin following criticism of his social media activity. The 22-year-old wing-back — a club-record transfer from Major League Soccer side New York Red Bulls — has faced criticism for his activity online relating to a variety of topics including gender identity and conspiracies around the COVID pandemic.

Defender John Tolkin has transferred to Holstein Kiel of the German Bundesliga from Major League Soccer’s New York Red Bulls.

Tolkin is referred to as "JMi" almost exclusively by teammates, friends and family (a reference to his middle name Michael). He revealed in 2023 that the nickname was given to him by his uncle when he was young and that he hardly answers to "John".

John Tolkin’s move to Holstein Kiel in Germany isn’t just another transfer in the world of soccer, it’s a bold gamble, a game-changer in the life of a 22-year-old with the talent and potential to shine on bigger stages. This move is going to change everything for the left-back from the New York Red Bulls.
