Santiago Castro

In January 2024, the player completed a transfer from Vélez Sarsfield to Bologna for a reported €12 million. By late 2024 and early 2025, reports linked to Inter and Juventus valued him between €25 million and €30 million. In March 2025, an offer from Inter, reportedly €20-25 million plus a player, was rejected. From March 2025 onwards, Bologna's asking price was consistently reported at €40 million amid interest from clubs like Inter and Juventus. A November 2025 report suggested a bid over €35 million would be required. Most recently, in March 2026, reports indicated Bologna's valuation is a minimum of €40 million. His Transfermarkt value was frequently cited at €35 million throughout 2025 and early 2026.

Our valuation is driven by Bologna's consistent and recently reiterated asking price of at least €40 million, which has been widely reported since early 2025. This figure is strongly supported by Santiago Castro's recent contract extension until 2030 and significant interest from multiple top clubs in Italy and England. His initial €12 million transfer fee in 2024 highlights a rapid appreciation in value, justifying the current high price tag.
