West Ham youngster Callum McNaughton has moved to AFC Wimbledon on a permanent basis.

The 20-year-old centre-half has been on loan at the League Two club since September and has extended his stay twice to make a total of 16 appearances in all competitions for the Dons.

The Bishop’s Stotford-born defender has been with the Hammers for six years and signed his first professional deal last summer.
