Shapourzadeh noted his positive impression of the combination of Jantunen's attributes, mentioning his size, athleticism, and dynamism. He also described him as a courageous goalkeeper who is comfortable with the ball at his feet and actively participates in build-up play. Jantunen stated he is excited for the new challenge, describing the club as a special football location with great fans. He added that he has learned a lot in Germany and is ready to take the next step in his career. The goalkeeper has 7 caps for the Finland U21 national team. According to Transfermarkt, his current market value is €300k.
