Rayo Majadahonda kicked off their first ever season in Spain's second tier on Sunday afternoon, slipping to a 2-1 defeat at Real Zaragoza.
The tiny Madrid-based club have a stadium capacity of less than 3,500, which means they will now borrow Atletico Madrid's Wanda Metropolitano this term, and they started on the road on Sunday.
A game against a Segunda veteran side in Zaragoza was always going to be tough, and two fist half goals from Jorge Pombo and Javi Ros set the hosts on their way to victory.
Then, a moment of interest for West Ham United; striker Toni Martinez, sent out on loan to Majadahonda by the Hammers, struck a fine goal on his right foot, drilling the ball in off the post late on to snatch a consolation goal.
The 21-year-old forward was making his Majadahonda debut as a half time substitute for Enzo Fernandez as Antonio Iriondo went looking for goals to get his side back into the game.
Martinez will be pleased to get off the mark after just 45 minutes of action, having endured on difficult loan spell back in his native Spain earlier this year, scoring just once in 11 games for Real Valladolid.
West Ham have had high hopes for Martinez since his 2016 move from Valencia, but he has made just three first-team appearances for the Hammers, and struggled through loan stints with Valladolid and Oxford United.
At 21, Martinez now needs to start showing that he can live up to his billing, and he got off to the perfect start with an impressive finish for his first Majadahonda goal on Sunday.
