Floyd Mayweather releases 'victory shirt' after beating Manny Pacquiao

Mayweather has never been averse to both trumpeting his achievements and making lots of money, so he decided to combine both in designing and selling what he described as a “victory shirt”.

The undefeated fighter already considered himself a greater boxer than established legends such as Muhammad Ali, Sugar Ray Leonard and Sugar Ray Robinson, so he clearly saw beating Pacquiao as merely confirmation of that fact.

But far from simply celebrating the high-profile win himself and with friends and family, he decided that the best way to bask in his own glory was to release an ‘official, limited edition victory shirt’.

Mayweather posted a photo of him posing with the T-shirt, with the garment proclaiming that he is “THE BEST EVER".

Alongside the photo, Mayweather wrote: “Thank you for all of your support. I’ve designed an official, limited edition victory shirt, available for just 2 weeks”.

Fans were quick to round on him for his assertion with 'judemccorry' among those arguing that Ali was superior, saying, "You will never be the best - Muhammad Ali is the all time great", while 'chelfer' added, "You may be unbeaten, doesn't mean you're the best ever".

The American is already the king of boxing merchandise with his ‘Money Team’ brand, but now he has attempted to cash in further in a typically bashful fashion.

It's hardly the first time that Mayweather has upset fans with his brash, flash style on social media, as this slideshow amply demonstrates.

Mayweather remains undefeated in his professional career with a record of 48-0, just one win shy of Rocky Marciano's iconic 49-0 career mark.
