Boxing legend looks unrecognisable in incredible throwback snap to childhood as fans joke ‘he never changed his shorts’

A BOXING legend looks completely unrecognisable in this throwback snap from their childhood.

Fans have been left joking that "he never changed his shorts" after the old photo was uploaded to Instagram.

The boxer in question has been a world champion in four different weight classes and is returning to the ring later this month.

He also has a professional record of 59-2-2 with 39 of his wins coming by way of knockout.

A current undisputed world champion, the fighter shared the snap of himself as a child in a yellow T-shirt and white shorts.

His iconic ginger hair is on full display in the throwback picture as he strolls down the street.

Alongside his post, he wrote: "Some things never change," as well as attaching a recent snap from the gym of himself wearing a similar outfit.

Still not guessed who it is? It is of course undisputed super middleweight world champion Saul "Canelo" Alvarez.

Reacting to Canelo's throwback snap, one fan commented: "You didn’t change the shorts either."

Another also joked: "He still has the same shorts."

Meanwhile, a third follower proudly hailed Canelo as "The pride of Mexico".

The 33-year-old is set to defend his world titles in Las Vegas on September 30 against undisputed super welterweight world champion Jermell Charlo.

Speaking ahead of the bout, Canelo explained: "It's a good fight, it's been talked about since a long time ago, and now I'm in PBC I think it's a good fight for the fans.

"I just like fighting, I like boxing and I like what I'm doing right now – making history."
