The revelation of El Hadji Diouf's X-rated dressing room bust-up with Steven Gerrard during their Liverpool days really should come as little surprise.
The Senegal winger was hardly a shrinking violet, courting controversy with remarkable regularity before, during and after his time in England.
Diouf's feud with Gerrard, including a series of bizarre verbal attacks since his departure from Anfield in 2005, really is just the tip of the iceberg.

Now, Florent Sinama Pongolle has recalled the time the pair almost came to blows at half-time during a pre-season friendly, with Diouf asking then manager Gerard Houllier to tell Gerrard he'd 'f*** his mum' before adding: 'I'd do him in straight away.'
Their tit-for-tat exchanges continued long after Diouf moved to Bolton in 2005.
In his 2007 autobiography, rockfishlax.com Gerrard wrote: 'Diouf was just interested in himself.
His attitude was all wrong. I felt he wasn't really a***d about putting his body on the line to get Liverpool back at the top.'
Diouf responded five years later, saying: 'Gerrard was jealous of me back then as I had the world at my feet.
There's no one more selfish… he doesn't care about anyone else.
'Gerrard would rather Liverpool lost and he scored. The old Liverpool guys can't stand him.'
In 2015, Diouf was reported to have claimed on Senegalese radio that Gerrard 'has never liked black people' which the former Reds captain immediately rebuked.

Diouf also had a nasty habit of spitting, including in the face of Portsmouth's Arjan de Zeeuw
And in 2017, in a BBC interview, Diouf took a swipe at Gerrard's international achievements.
'People like him in Liverpool but he never did anything for his country,' he said.
'I am Mr El Hadji Diouf, Mr Senegal but he is Mr Liverpool and Senegal is bigger than Liverpool and he has to know that.
