Leo Sauer is making serious waves. The 19-year-old Slovak winger, on loan at NAC Breda from Feyenoord Rotterdam, is one of the brightest prospects in Slovakia. Winner of the Peter Dubovský Award for the best Slovak player under 21, he is backing up the hype with performances that demand attention.
Sauer’s stock has skyrocketed. According to the CIES Football Observatory, his market value has surged from €2 million to €14 million since September–one of the biggest jumps outside Europe’s top five leagues. Transfermarkt remains more conservative, valuing him at €5 million, but even that figure seems due for an upward revision, writes Hospodárske Noviny.
At Breda in the Netherlands, Sauer is the club’s most valuable player, and his impact is evident. In 22 appearances, he has scored five goals and registered two assists. His performances have drawn praise from experts, media, and fans alike. Feyenoord, who loaned him out for game time, may already be questioning that decision.
“Leo’s reputation in the Netherlands is growing fast. Even people within Feyenoord’s structure are wondering why they let him leave,” his father and agent, Július Sauer, told the Slovak daily.
With a contract in Rotterdam until 2028, the expectation is that Sauer will return to Feyenoord next season. But interest is growing beyond the Eredivisie. “Other foreign clubs are asking about him,” his father admitted. “The key was for him to play regularly and develop. Compared to September, he’s in a much better place.”
Breda’s defensive setup has also helped him refine that side of his game, something Feyenoord may benefit from next season.
On the international stage, Sauer has already made four senior appearances for Slovakia. He remains eligible for the U21 Euros this summer, hosted by Slovakia. His involvement, however, depends on national team coach Francesco Calzona and Feyenoord’s approval.
“He’d love to play and help the U21s,” his father said. “Now we wait for the decision.”
Whatever happens, Sauer’s trajectory is only pointing in one direction – up.
