Max Dowman is the story of the international window in the transfer market. The 16-year-old Arsenal forward has seen his Expected Transfer Value jump €53.4 million in a month to €63.5 million, according to data analytics firm FootballTransfers. No under-18 player in world football is worth more.

The leap comes on the back of a run of senior-level breakthroughs for Arsenal and a historic step up with England. On Friday he became England Under-21s’ youngest debutant at 16 years, 10 months and 13 days, surpassing Jude Bellingham’s record off the bench in a 1-0 friendly defeat to Portugal U21 at Ashton Gate in Bristol. The FootballTransfers piece noted he had returned three goals and one assist for his club in 676 minutes this season.

Wirtz’s €37m slide at Liverpool

Florian Wirtz has moved the other way. The Germany playmaker, signed from Bayer Leverkusen in the summer of 2025 for around £116 million, has lost €37.2 million in value this month on the FootballTransfers model. Alexander Isak has now overtaken him as Liverpool’s most valuable player.

Wirtz has struggled for consistency at Anfield since his move, with factors ranging from a loaded attacking cast to the aftermath of Diogo Jota’s death cited in recent coverage. He did go into the international break with a goal and an assist in Liverpool’s 3-1 win over Crystal Palace, and a sharp Germany display suggests the slide is not terminal.

Chelsea’s Garnacho problem

Chelsea’s issue is on loan at Aston Villa. Alejandro Garnacho’s valuation has fallen roughly 25 per cent in a month, from about €40.5 million to €28.7 million, after a cold start at Villa Park: four appearances and no goals. He joined on a season-long loan with a conditional obligation to buy, a clause now reportedly in doubt.

FootballTransfers’ Robin Bairner wrote that the Argentine “is already threatening to become a chronic issue” for Chelsea, who carry a six-year contract commitment on a player producing little in the loan shop window.

Hojlund scores twice in Braga

Rasmus Hojlund delivered the sharpest reminder of how quickly form can change. The Napoli striker scored twice in Denmark’s 4-1 win over Portugal in Braga on Saturday, the first Portugal match of the post-Cristiano Ronaldo era under new head coach Jorge Jesus. He volleyed in shortly after half-time and drilled a low finish past Diogo Costa soon afterwards.

The 23-year-old had scored just three Serie A goals in 11 matches for a struggling Napoli side under Massimiliano Allegri before leaving for international duty. His FootballTransfers valuation, which the November report placed outside the headline movers, will be worth another look when the next update lands.
