What happened: Sandro Tonali is on his way back to England to finalize a switch from Newcastle United to Tottenham Hotspur worth a reported €116m (£99.5m) including bonuses, with roughly €108m in fixed fees. The transfer makes him the most expensive Italian footballer in history and Tottenham's record signing.

Why it matters: The deal reaches back to Tonali's 2023 exit from AC Milan, who inserted a 10% sell-on clause when they sold him to Newcastle. That clause now converts a routine sale into a payday for a club no longer involved, underscoring how front-loaded modern transfer accounting rewards the selling side long after a player moves on.

What to watch: Watch for official confirmation from both clubs once Tonali completes his medical in North London, and how Milan books the incoming windfall against their summer spending.
