Morgan Rogers in Chelsea medical as Arsenal left reeling after hijack

Morgan Rogers is undergoing a medical at Chelsea, according to reports, in a shock transfer hijack that has left Arsenal reeling. The Gunners had made a clear demand from Mikel Arteta to sign the player, but a combination of Chelsea's late intervention and World Cup injury woes scuppered the deal, leaving Arsenal to turn their attention to a centre-back shortlist. Meanwhile, Manchester United have sealed a transfer coup by signing England Under-18s winger Tynan Thompson from Tottenham. The summer window continues to deliver drama as clubs scramble to strengthen their squads.
