Following the video, Fernandez faced intense criticism, with several Chelsea players unfollowing him on social media.
Tony Cascarino has said that the issue could lead to a dressing room crisis if the club does not act fast.

Cascarino ask Chelsea to sell Enzo
According to former Stamford Bridge star Cascarino, Fernandez has given the Blues little option but to sell him.
He believes that Fernandez's remarks will permanently separate him from the other players in the changing room.
Cascarino told talkSPORT, as reported by the Sun, “It's going to be tricky. I look back at when I was at Chelsea in the 90s and I'm not sure that dressing room would be OK with what Enzo Fernandez did.
“That’s a tricky one to handle. I think Chelsea have got a major decision on whether they actually keep Enzo Fernandez.
“Having players not happy with a guy in the dressing room, I’m not sure there will be many that comfortable with some of the things that have gone on. There’s no excuse for that to go out. It’s not going to sit well with the other players is it?
“I don’t know how you can handle it because there will be players who can’t forgive. There might be some who can move on despite not liking what happened.
“You don’t need everyone to like each other at a club but this is a really, really tricky one. Some players won’t want to move on or make it work."
Chelsea may face a dressing room crisis when the season starts after Wesley Fofana’s online criticism of Enzo for racism.
Fernandez has subsequently expressed regret for his involvement in the hurtful chants but it is unclear if he will be able to mend fences with Chelsea supporters, particularly the team's sizable number of French players.
