If Los Angeles Lakers legend Shaquille O'Neal is Muhammad Ali, then Charles Barkley is Sonny Liston—at least according to Shaq.

Shaq was spotted on Thursday watching the Las Vegas Aces versus Phoenix Mercury game in Nevada, and interestingly, his wardrobe of choice turned heads. After all, even off the court and outside the NBA on TNT Studio, he's trolling Barkley.

The Lakers great was seen wearing a T-shirt with an edited photo of the iconic Ali knockdown of Liston. Shaq was Ali in the edited art, while Barkley was Liston lying on the canvass.

Now, where can we get that shirt?

Shaquille O'Neal is delivering knockout blows to his “frenemy,” with whom he has had a lot of heated and funny exchanges. The two often trade jabs at each other, with O'Neal known for always rubbing it to Chuck his lack of rings.

It remains to be seen how Chuck will respond to the trolling, but it's doubtful he will just let it slide. After all, he's still as competitive as he has ever been even after his playing days.

With the 2021-22 NBA season weeks away and the preseason coming soon, though, fans won't have to wait for long to see the two legends go at it again. Hopefully, though, it's Sir Charles who delivers a haymaker to the former Lakers big man.
