Inaki Williams said he was racially abused by Espanyol supporters during a 1-1 draw.

Williams said the incident occurred as he was subbed out in the 69th minute and walking in front of Espanyol ultras.

"I leave here feeling sad because of the draw and because I've been subjected to racist insults. It's something that no black player, or any player, wants to hear. It's completely out of place," tweeted Williams following the match. 

Espanyol said that they would investigate the incident.
