Kevin Mac Allister

In April 2026, multiple reports mentioned a Transfermarkt valuation of €10 million, with one suggesting Union SG would likely agree to a transfer for that amount. Previously, his Transfermarkt value was reported as €7.5 million in November 2025, and his market value was noted at €7 million in July 2025 and €6 million in May 2025. His last completed transfer was from Argentinos Juniors to Union Saint-Gilloise in July 2023 for a reported fee of €1.5 million.

Our valuation is driven by multiple consistent reports from April 2026 citing a market value of €10 million for Kevin Mac Allister, a figure Union Saint-Gilloise would reportedly accept. This represents a significant increase from his €1.5 million transfer fee in July 2023, supported by strong performances and widespread interest from several Premier League clubs, which solidifies the €10 million estimate as a credible benchmark.
