The chance of Gabriel Batistuta coaching in the A-League is becoming increasingly unlikely with Adelaide United close to appointing Marco Kurz from Germany as their next head coach, instead of the Argentinian star.

The former Bundesliga coach is emerging as the frontrunner to replace Spaniard Gui Amor as the new head coach of Adelaide and is understood to be close to agreeing terms with the club. While contractual details are yet to be concluded, it's understood Kurz's deal could be finalised during the week when representatives of the club arrive in Europe to finalise negotiations.

The Reds declined to comment when contacted by Fairfax Media on Monday morning but confirmed a German coach is certainly of interest.

Should Kurz sign, it will be his first stint coaching outside his native country where he's most remembered for coaching FC Kaiserslauten, earning promotion to the Bundesliga in 2010. He spent three seasons at the Fritz-Walter Stadion before short, yet unsuccessful, stints coaching Hoffenheim in the top tier, as well as Ingolstadt and most recently Fortuna Dusseldorf in the Bundesliga 2. He had previously spent three years at 1860 Munich, coaching their second team and their senior team.
