League Two club Crewe Alexandra have signed Callum Bullock from Manchester City.

The 18-year-old defender has joined Alex Morris' U23 side on loan until January.

Bullock, who is part of City's U23 squad, made his Crewe debut when starting in Wednesday's U23 loss to Cardiff City, playing 65 minutes.

The teenager is eligible to be called up to Steve Davis' first-team should Alex need his services in the seniors.
