The 16-year-old made the move to Selhurst Park when he was just 13, with Palace forking out £60,000 to prise the highly-rated attacker away from Millwall.
Palace reportedly fended off stiff competition from a number of leading English and European sides in order to land Atta, but the Eagles appear to have a fight on their hands if they are to keep hold of the teenager.
According to the Daily Mail, Liverpool and Man City retain an interest in Atta, who is eligible to represent both Italy and the Ivory Coast, although he currently occupies a spot in England's Under-16 squad.
However, the report claims that the two dominant forces in the Premier League are not the only ones keeping a close eye on developments, with Bundesliga trio Augsburg, Bayern Munich and Borussia Monchengladbach all interested as well.
Atta cannot pen professional terms at Palace until he turns 17, but the teenager is understood to have committed his future to the Eagles by signing a scholarship deal back in July.
