Ngoyi arrived at Elland Road midway through last season, signing on a double loan-deal with Sol Bamba, but he failed to make much of an impact.
He managed just one appearance for the Whites, owing to some long-standing injury problems, and whilst Bamba has reportedly been signed from Palermo on a permanent basis, it does not look as if Ngoyi will be heading back to Yorkshire.
His lack of appearances and ability to impress has not lowered the interest in him though, with one club reportedly keen on signing the holding midfielder.
They are playing in Europe once again next season, and have targeted the 27-year-old former French youth international as a player to improve their midfield.
He has experience of European football, and has shown to have talent when not being kept on the sidelines by injury, making him a strong signing for Asteras, especially as Palermo look to have no qualms concerning his summer sale.
There are yet no confirmations that Leeds have entirely pulled out of the race to sign Ngoyi, but it looks as if he could swap failing to play games in the Championship for regular first-team football in the Europa League.
