The 29-year-old has found it hard to replicate the form he showed in his first spell with the La Liga club.
He has scored just five goals in 21 appearances in all competitions this season - and the last of those came back in mid-November. This has made him a target for criticism from some sections of the crowd who believe he is not good enough to be playing, reports The Sun.
Fans have daubed messages on the walls in a residential neighbourhood calling for Perez to be sacked.
One disgruntled punter sought out a residential area where the striker had lived to take his anger to another level.
The message "Lucas Perez - Get out of our club" was daubed on the wall in a clear attempt to single the player out.
