Crystal Palace have signed midfielder Will Hughes from Watford for a fee of around £6m.
The fee for the 26-year-old, who has signed a three-year deal, could rise to £10m with add-ons.
Hughes has become Patrick Vieira’s sixth summer signing at Selhurst Park.
“They’re not just planning for the here and now, which is obviously important,” Hughes said.
“But they’ve got a big project going on here so it’s exciting to be part of it,” he added.
The former England under-21 player joined Watford in 2017.
He made 118 appearances for the Hornets and was entering the final year of his contract at Vicarage Road.
The Eagles have been rebuilding their squad under new boss Vieira after a number of players left at the end of last season when their contracts expired.
Palace, who have had 22 shots across their first three games of the season but have only hit the target five times, remain in the market for a striker.
