Toni Martinez will spend the remainder of the 2018/19 campaign on loan with Spanish La Liga 2 side Lugo.
The 21-year-old striker makes the move after being recalled from his loan at fellow second tier team Rayo Majadahonda, where he spent the first half of this campaign.
Martinez played 18 times for Majadahonda, scoring twice in their first ever campaign at La Liga 2 level, adding to the experience gained from his loan at Real Valladolid last term.
Lugo are currently 14th in the La Liga 2 table and take on Malaga this Saturday.
West Ham United wishes Toni all the best for his time with Lugo.
