Celtic made a last-minute attempt to sign Ognjen Ugrešić from Partizan after the club had accepted an offer from PAOK. The Glasgow-based club proposed a deal worth €6,500,000 plus €1,500,000 in bonuses and a 10 percent sell-on clause. Partizan rejected the offer, with president Rasim Ljajić stating they had already made a commitment to PAOK.
