Simeone, who has been capped 106 times by Argentina, played for Inter between 1997 and 1999 and he has said that he always planned to coach the Italian giants.
"Sooner or later, I will coach Inter," Gazzetta dello Sport quotes Simeone as saying.
"Even before going to Atletico I always said that one day I would return as manager.
"Everything happens in its time, but surely one day I'll see you in Milan."
Inter are currently fourth in Serie A.
