Leo Castledine

In January 2026, multiple reports suggested Chelsea were seeking a fee of around £1 million (approximately €1.2 million) for a permanent transfer. This valuation was mentioned in the context of widespread interest from several Championship clubs, including Watford and Bristol City. Later in January 2026, a permanent deal with Middlesbrough was reportedly agreed, although the final fee was not disclosed in the available data.

Our valuation is driven by multiple consistent reports from January 2026 stating a Chelsea asking price of around €1.2 million (£1 million) for Leo Castledine. This figure is supported by significant reported interest from at least six Championship clubs, creating a competitive market, and culminating in an agreed permanent transfer to Middlesbrough. His strong loan performance at Huddersfield further solidifies this valuation.
