Bundesliga side VFB Stuggart have reportedly open talks with Leicester as they attempt to add 22-year-old to their squad before the end of the transfer window.
The Ghana international played a small part in the Foxes’ 2016 Premier League title success following his £6million move from FC Copenhagen that January.
Amartey, 22, went on to score once during 34 senior appearances last season.
Stuttgart now want him to strengthen their squad following promotion back to the Bundesliga.
And reports in Stuttgarter Zeitung claim club officials have opened talks with their King Power counterparts about a deal for Amartey.
The star is under contact until 2020 with Craig Shakespeare’s side.
The African powerhouse is one of ten midfielders battling for a place in the squad this season.
He is understood to be tempted by the prospect of moving to Stuttgart.
