Former Liverpool captain Gerrard retired on Thursday, but Diouf has reignited his war of words with the 36-year-old.

Former Liverpool striker El-Hadji Diouf has again launched a scathing attack on Steven Gerrard after the latter announced his retirement from the game.
Gerrard called time on his career after leaving LA Galaxy racking up almost 750 total appearances, while Diouf was derided for his time at Anfield after moving on the back of a successful 2002 World Cup with Senegal and is best-known for controversy rather than goalscoring.
The pair notoriously fail to see eye-to-eye and have previously attacked each other in the media, with Gerrard writing in his autobiography Diouf, "“did not care about football and about Liverpool”.
And while Diouf admits he respects Gerrard as a player, he does not respect the 36-year-old as a person.

"People told me at Liverpool, there was some guys you could not touch, but I touched them," he told SFR Sport, as you can see in the video below.
"That is why it was complicated for me. When I arrived I showed [Gerrard] he was nothing at all. He was nothing at all.
“I asked him to tell me in which big competition, Euros or World Cup, people think about him."
Co-pundit Emmanuel Petit defended Gerrard by pointing to his captaincy and performance in the Champions League victory over AC Milan where Liverpool were 3-0 down, but when he couldn't remember what year the 2005 triumph was, Diouf sprung to attack again.

"Here is the proof, even you cannot remember. You are talking about Euros and World Cup. Today I owe you respect [Petit], I owe respect to Mr Zidane because you did win the World Cup.”
“I repeat. I respect the player, very big player, but the man, I do not respect. And I told him, I let him know that. With all my respect I let him know.
Diouf also explained that he took issue with Gerrard going to speak with then manager Gerard Houllier over an incident.
“Then as you know, there were some brown-nosers, who went to the manager to repeat what I said," Diouf added. "That was the real problem.
"When Gerrard did that, we had an argument, like real men. That is why he does not like me. He knows I say what I think, that when it is not right, no problem, I am up for it.
“He could not, he was afraid of looking into my eyes."
The latest comments from Diouf will no doubt be brushed off by Gerrard who is rightly celebrated as one of England's greatest players and the world's best midfielders.
In a career that has brought the pinnacle of the Champions League, two FA Cups, three League Cups, a UEFA Cup and a whole host of individual honours, he'll take Diouf's comments with a pinch of salt and focus on launching a career for himself in coaching.
