Michael Johnston

Available data indicates that in August 2025, the player's market value was estimated by Transfermarkt at €3.0 million. This followed his completed transfer from Celtic to West Bromwich Albion in August 2024 for a reported fee of €3.5 million. More recent reports from 2025 and 2026 mention a near-transfer to Flamengo, but do not specify a fee.

Our valuation is driven by two key data points: Michael Johnston's transfer from Celtic to West Bromwich Albion for €3.5 million in August 2024 and his more recent Transfermarkt valuation of €3.0 million. While he is reportedly performing well, a collapsed transfer to Flamengo due to medical concerns suggests the market may be cautious, justifying an estimate at the lower end of this recent valuation spectrum.
