Hughes could face FA disciplinary chiefs for misconduct or bringing the game into disrepute. BBC Match of the day producers decided to leave the incident in their coverage where lip readers could clearly make out the insult.
Arnauotvic was constantly abused by Stoke fans throughout the game which led him to celebrate his goal against his former club as well as making the crossed hammers sign and touching the West Ham badge on his shirt to show them he is a proud Hammer.
The goalscorer went straight down the tunnel after his substitution as Stoke fans threw items at him as he came off the pitch.
Mark Hughes is now the 1/4 odds-on favourite for the sack as a Premier League manager.
New found love for Marko Arnautović. Despise Mark Hughes as well as Stoke. Only ever turn up against us.pic.twitter.com/mHX6XqqMVO
