Aston Villa are willing to listen to offers for Jhon Duran if they can find a suitable replacement this window, and the Colombian has interest from AC Milan.
However, the club may encounter difficulty finding a candidate that can offer a robust back-up option to first-choice striker Ollie Watkins during the January window.
Watkins has been in blistering form this season, effectively shutting Duran out of Emery's immediate plans.
Mail Sport also understands that the head coach and his player have sometimes not seen eye to eye, with the 20-year-old thought to be frustrated with decisions to substitute him at various points during Villa's European season.
