David Moyes did not attend Chelsea's FA Cup replay against Norwich City to scout Michy Batshuayi, while the West Ham boss has dealt a blow to the Blues in their reported chase of Andy Carroll.
Belgium international Batshuayi has been strongly linked with a move away from Stamford Bridge in January after struggling to make an impact at Chelsea in the year-and-a-half since moving from Marseille.
Batshuayi – who scored for Chelsea against Norwich – had been suggested as a potential makeweight in a deal to take Carroll the other way, with Antonio Conte's side linked with several surprising options, including Stoke City veteran Peter Crouch.
