J. Mvuka

In February 2026, a permanent transfer to Celtic was reportedly agreed at various figures, most consistently around £3 million (€3.5 million), but also mentioned as high as £4.5 million (€5.3 million). This deal was renegotiated into a loan with a reported option to buy for approximately £3 million (€3.5 million) after a medical issue arose. His market value was listed by Transfermarkt at €2.00 million in May 2026. The available data shows his transfer from Bodø/Glimt to Lorient in January 2023 was for a fee of €5.5 million.

Our valuation for Joel Mvuka is primarily driven by the recently failed permanent transfer to Celtic. While a fee around €3.5 million (£3 million) was widely reported, the subsequent discovery of a medical issue and a highly unsuccessful loan spell have significantly lowered his market value. The current Transfermarkt valuation of €2 million aligns with this downturn, forming the basis of our estimate, which sits slightly above that floor to account for his remaining potential.
