Costinha's switch from Olympiacos to Brighton is effectively done. The 26-year-old Portugal defender has agreed a five-year contract that runs until June 2029, joining the Premier League side after a spell in the Greek Super League. The fee under discussion sat in the £9.4m–£11m range, comfortably above the player's market value of around £6m, and the deal is now at the imminent stage — the formalities of an announcement rather than a negotiation still up in the air. The sourcing here is strong. BBC Sport, a benchmark outlet, has reported the signing outright, stating Brighton have secured the defender on a five-year contract. That has been reinforced by Giannis Chorianopoulos, a reliable voice, who has been working with Brighton's official website on coverage of the move. When a benchmark reporter states a deal as fact and a credible local source points to the club's own channels, you are well past the rumour phase. The 97% reading reflects exactly that. It means the engine sees this as all but certain to complete — the contract length is known, the fee is settled, and the announcement framing is already in motion. The small remaining margin simply accounts for the rare late hitch any move can hit before paperwork is fully ratified. There is no real obstacle holding this back. Costinha's past moves were modest by comparison — Porto to Dinamo Moscow for £3m in 2005, then Dinamo Moscow to Atlético for £5m in 2006. Against those, a fee around £11m marks a clear step up in valuation. Watch for the official confirmation and the £11m figure being formally logged once the medical and registration clear.
