AC Milan are watching closely Simone Zaza's struggle with West Ham.

The former Juventus striker has battled to make an impact since his arrival last month.

Zaza has been derided and mocked by pundits for his efforts as the Hammers have struggled in the opening games of the new season.

Premium Sports says Milan chief Adriano Galliani is monitoring the situation and has plans of making a move to bring Zaza back to Serie A as early as January.

Zaza could arrive as a replacement for Luiz Adriano, who has attracted enquiries from Russia this week.
