The infamous incident has long been seen as the key moment when the 2013-14 Premier League title slipped from Liverpool's grasp, and Diouf stuck the boot in when asked about Gerrard in an interview with SoFoot.com (via Eurosport's Ben Lyttleton):
And do you think Gerrard means it when he says that El-Hadji Diouf is not a very good player?
I carried the national team for many years, 14 million fans on my shoulders. When we won, it was thanks to me, when we lost, it was my fault. What I represented for Senegal, he [Gerrard] never managed 100th of that for England. He has never done anything in the World Cup or the Euros.
When I arrived at Liverpool, seeing as I just did what I wanted, [Gerrard] thought that I did not respect the club. But he downright killed his team by slipping against Chelsea. If Liverpool has never won the Premier League, it's no accident. What goes around, comes around.
The former Senegal international also attacked Liverpool legend Jamie Carragher in the interview: "The difference between Jamie [Carragher] and me is that I am a world-class player and he is a s--t. The type of s--t that writes a book and mentions me all the time. Me, in my book, he does not warrant one phrase: he's a f--king loser."
And upon being accused by Gerrard of having "no real interest in football" in the Englishman's autobiography—as well as being named the Liverpool signing he "liked least"—Diouf responded by accusing the LA Galaxy star of racial prejudice, per Senegal’s Radio Futur Media (h/t the Sun's Tom Gardiner).
The Telegraph's Chris Bascombe commented on the alarming regularity of the 35-year-old's outbursts:

Diouf has long had a controversial reputation, known less for his playing talents as a forward than for his numerous disciplinary problems.
In his spell at Anfield between 2002 and 2005, he scored just three league goals, per Sky Sports' Duncan Alexander.
He did, however, make headlines in other ways, most infamously spitting at a Celtic fan during a match at Parkhead in the UEFA Cup.
Inevitably, Diouf has not dropped his grudge against the English defender, or the north-east club, per SoFoot.com (via Lyttleton): "I spent six s--tty months there. We were not a team. There were little w--kers in the group who thought they were the best but they were crap. Anton, he was the No. 1 w--ker."
He also described an extraordinary incident in which he came across Ferdinand again in a Manchester nightclub:
I ignored him [Ferdinand]; that must have bothered him, so he came over to test me. I'm a man, I can defend myself. If there is a crazy guy who wants to take me on, I'll show him that I'm crazier than him. The first of his friends who came too close to me, he ended up running away. Since I was drinking champagne, I broke my glass and I attacked them…I came out unscathed, and since then, the club now uses plastic glasses.
It is unlikely that Diouf's latest comments will have any great effect on Gerrard, Carragher or Ferdinand, but it seems he is far from finished with taking swipes at former team-mates.
