Iván Calero's move is done. The 31-year-old Spanish defender has joined Real Oviedo from Cultural Leonesa, stepping up into La Liga on a deal that runs until 30 June 2028. There is nothing tentative left here: the signing is confirmed, the contract length is set, and Calero is now an Oviedo player rather than a target being chased. The confirmation comes straight from Real Oviedo themselves, posted moments ago. As sources go, you cannot do better than the club announcing its own business — this carries a credibility of 95 out of 100 and removes any doubt about whether the transfer is real. It is the official word, not a second-hand whisper. That is why the engine reads this at 100%, the very top of the scale. The percentage reflects certainty rather than likelihood: when the buying club has formally announced the player and the contract terms are known, there is no remaining hurdle — no fee to agree, no medical to pass, no rival to fend off. Everything that needed to be true for completion is already true. The money fits Oviedo's recent pattern of measured spending. They brought in players from Red Star for £2m, from Villarreal for £1m in 2024, and from Girona for £1m in 2025 — modest, sensible fees rather than headline splurges. Calero himself is no stranger to this market, having moved from FC Cartagena to Real Zaragoza for nothing in 2024. With the deal confirmed, the next things to watch are simply Calero's unveiling, his shirt number, and how quickly he is integrated into the La Liga matchday squad.
