Newcastle United complete the signing of 18-year-old midfielder Sean Steur from Ajax, sources report. Multiple outlets say the transfer is worth £23 million, with at least one report describing the package as potentially rising to about €27 million depending on conditions. Newcastle and Ajax reach an agreement in principle earlier this week, and Steur is shown arriving in Newcastle to complete the move. Reports also say Steur agrees personal terms and signs a contract running to the end of June 2031, which aligns with a five-year deal cited by one outlet. The Athletic reports that Steur will wear the number 14. Sky Sports and the BBC also describe the transfer as a teenager deal for a central midfielder. Separate reporting notes Steur made 25 first-team appearances for Ajax last season. Coverage of the move also places it in the context of Newcastle continuing to reinvest in their squad following the departure of Sandro Tonali to Tottenham, with Newcastle taking additional steps in their recruitment strategy.
