This one is done. Ivan Ćubelić, the 23-year-old Croatian midfielder, has joined HNK Rijeka from Slaven Koprivnica, putting pen to a four-year contract. There is nothing left to negotiate: the move is confirmed, and Ćubelić himself has framed his arrival around Rijeka's ambition, saying the club's goals are always the highest and that drew him in. He has promised supporters desire, sacrifice and full commitment in every moment on the pitch. His deal runs the length of his stay, with terms keeping him at the club well into the future. The announcement comes straight from Rijeka's own official channel, complete with the signing imagery and Ćubelić's first words as a player. As primary sources go, this is as authoritative as it gets — a club confirming its own business carries top-grade credibility, and there is no ambiguity or second-hand speculation to weigh here. The probability sits at 100% because there is simply nothing left to happen. The contract is signed, the player has spoken, and the club has confirmed it. This figure does not predict a future event; it reflects a deal that has already crossed the line. There is no fee dispute, no medical pending, no rival club to muddy matters — only a completed transfer. The money and the move fit Rijeka's pattern. The club has previously brought in players from Dinamo Zagreb for £1m, from Hoffenheim for £1m in 2019, and from Real Sociedad B for £1m in 2022. Domestic, modest-fee additions like this are squarely in keeping with how Rijeka build. From here, watch only for Ćubelić's integration: his first squad inclusion and competitive debut in Rijeka colours.
