The striker is a free agent at the moment and managed to gain shape after a long injury break, by training on his own.
In 2001 Amoah was transfered for 3.93 millions Euros from Swiss club St. Gallen to Sturm Graz, but failed to impress. On 1 September 2003 Sturm Graz concluded a loan contract with Salzburg (until 31 May 2004) from wich Amoah was dismissed on 18 February 2004 without any notice. Amoah sued Sturm Graz because of not paying him salaries, and they finally came to an agreement out of court.
