Alexander Isak's market value has risen the most out of any footballer in the world since the start of 2025, it has been claimed. The 26-year-old signed for Liverpool in a British record £125m transfer in September.

Since his move to Anfield, Isak has scored once in eight appearances. He found the net for the first time in a Reds shirt during the Carabao Cup third round tie against Southampton last month.

Although he hasn't set the world alight since he signed for Liverpool, Isak has seen his value skyrocket, according to SportingPedia's latest report. At the beginning of the year, Isak's market value stood at £65million, but now, following a goal-ridden second half of the season at Newcastle United, he is worth £121.6m.

That is an astonishing £56.6m rise - more than anyone else on the planet...
