His brand, which made him known to the public beyond football, includes his strong Rhineland accent and, before his weight loss in 2020, being obese.
In Rhine-Erft he was a football player and after a serious injury became a youth coach (SpVg Frechen 20 Franken Lövenich and BC Efferen).
Especially in the 2001/2002 season, when Leverkusen finished second in the Bundesliga, DFB Cup and Champions League, earned the club the nickname "Vizekusen".
[2] Calmund was one of the first to realize the possibility of recruiting top players in East Germany as soon as the Berlin Wall fell on 9 November 1989.
He has said: "The GDR had top class youth academies with full-time coaches, stuff that we in the West could only dream of in the 1980s".
[4] Calmund is considered a prime mover in mining East Germany for talent during the period known as Die Wende.
Additionally, he was able to win the Brazilians Paulo Sérgio, Jorginho, Emerson, Zé Roberto, Lúcio and Juan, as well as Bulgarian Dimitar Berbatov for the club.
[6] In addition, Calmund claims to have paid Graul, at the request of Bayer Leverkusen, €350,000 from his private assets.
[7] The Cologne public prosecutor held proceedings against Calmund for a breach of trust, but the matter was settled with the payment of a €30,000 fine .
[11] From 1 February 2008, Calmund presented a video blog on his website Calli.tv, in which he published his weekly assessments of the respective Bundesliga match day and other football events.
He undertook several diet attempts, which, however, led to weight gain in the medium term due to the yo-yo effect.
