The second offer, around 15 million euros, was rejected by Celtic but Atalanta, as mentioned, is not giving up. Working to facilitate the operation between the two clubs is the intermediary Blash Hosseini.
O'Riley (midfielder born in 2000) has already approved the possible transfer to Atalanta and already has a basic understanding with the Bergamo club for a long-term contract, most likely five years. The agreement between the two clubs now remains to be found, with Atalanta insisting on O'Riley.
