Chelsea have agreed a £117 million deal to sign midfielder Morgan Rogers from Aston Villa.
The fee represents a club record for Chelsea, and the player is set to sign a six-year contract.
Rogers will undergo a medical with the London club on Monday to complete the transfer.
Arsenal had pursued the England international, but Rogers opted to join Chelsea instead.
Coach Xabi Alonso played a key role in persuading the midfielder to make the move.
Chelsea have lacked creativity in the final third, and Rogers addresses that need directly.
The 23-year-old has been one of the Premier League's standout young players over the past two seasons.
He helped Aston Villa win the UEFA Europa League and secure a top-four finish last campaign.
The transfer deals a significant blow to Arsenal, who remain in search of a dynamic attacking presence.
The Gunners require greater cutting edge in the final third and must now shift to alternative targets.
Rogers possesses the attributes to develop into a global superstar with regular first-team football.
Chelsea endured a disappointing season and view strategic signings as essential to their recovery.
