Doncaster Rovers face competition from Spain for Manchester United striker Kiko Macheda.
The Daily Star says the 22-year-old scored three goals during his time with Paul Dickov's side, having joined Rovers on a one-month deal in September.
Doncaster are thought to be eager to take the striker back on loan from United after his injury heals, but now face increasing interest from other clubs.
New reports in Spain today claim Rayo Vallecano are interested in bringing the 22-year-old to La Liga to help strengthen their depleted frontline.
