Live updates on transfer rumours.
TransferFeed valuation based on market analysis.
In January 2026, reports mentioned a bid of €20 million (£17 million) from Arsenal. Around the same time, his Transfermarkt value was listed as €10 million. Earlier, in September 2025, it was speculated that his transfer could generate at least €20 million for his club.
Our valuation is driven by consistent reports from late 2025 and early 2026 pointing to a €20 million fee for Vasilije Kostov. This is supported by a reported offer from Arsenal of that amount and the selling club's own expectations. The player's young age, strong performance, and long-term contract until 2028 solidify this valuation.
