Ibrahim Farah, 22, has come out and criticised Malky Mackay and how he treated his squad during his reign at Cardiff City.
The ex-Cardiff midfielder spoke on Twitter about his personal incidents where Mackay personally targeted Farah, and even brought race into the conversation by calling him a "Wee Egyptian" and laughing at him.
"Malky Mackay is racist wish the people at Cardiff City seen it sooner," Farah said on Twitter.
"Malky Mackay always use to call me a wee Egyptian and laugh his head of no one knows what happens behind the scenes in football clubs.
"At the time when you're a young pro no one will listen. People would listen to the manager and not me so I chose to keep my mouth shut.
"Every manager has his views on his players I wasn't his type of player but to treat certain player on how he did at Cardiff was disgusting.
"Oxford away a young Somali boy was at the gates and Malky shouted look at that black Somali kid at the gates, look it's ibby brother. He then started laughing him and coaching staff.
"Cardiff were treated poor by Malky and his coaching staff were scared to speak around him let alone ask him for help on the training pitch."
Farah opened up after recent reports that Mackay sent racially aggravated text messages to his Cardiff backroom staff, and used to repeatedly joke about various racial situations.
Despite Mackays 'Egyptian' comments, Farah is actually born and raised in Wales, with his parents being from Somalia.
The youngster finished his Twitter rant with a Tweet to Cardiff FC.
"Hope Cardiff City get back to the prem as I'm a cardiff fan and a cardiff lad the club deserves to be back in the prem."
