With the eagerly awaited showdown between boxing legend Floyd Mayweather and UFC superstar Conor McGregor only days away, the war of words between the pair has continued.

Both fighters are in the final stages of their preparation and both camps will be more focused than ever on ensuring their fighters are ready for the showdown.

Nothing will be left to chance and with them both eager to prove their fighting superiority over the other, they will be laser focused and will do everything in their power to be ready for August 26.

In both boxing and UFC, weight classes are sacred.

As a result, both Mayweather and McGregor will need to make the 154lbs weight on Friday or face hefty fines.

Floyd Mayweather, who is well known for his boxing intelligence and attention to detail, has never had trouble making weight. He is renowned for walking around just above his fight weight and usually coming in a pound or two under the limit.

The verbal back and forth between both fighters has been the source of much entertainment, and Mayweather recently wasted no time in continuing it.

He recently claimed the Irishman was struggling to make the limit, even going as far as to claim that McGregor was a massive stone overweight.

McGregor did not take too kindly to the jibe and fired back, fiercely saying: "Tell him to shut his f****** mouth. He knows nothing, the fool of a thing."

He went on: "Let him keeping praying, praying for weight, praying for fatigue, praying for me to take a backwards step. All he’s doing is praying to the new god of boxing. 

"My weight is phenomenal, when have I ever missed weight? Let him think what he wants."

Choice words indeed.

McGregor, who will make his professional boxing debut on Saturday, will be eager to make history by toppling Mayweather.

He will have his work cut out for him, however. Mayweather is a supremely skilled operator and his defensive skills are second to none.

However, if McGregor stops Mayweather, it will go down as one of, if not the, greatest sporting upset of all time. 

A confident McGregor continued to fire back at Mayweather saying: "I'll be a lot heavier than he is and make no mistake, he’ll feel every pound"

He added: "I believe I’ll knock him out early, in one or two rounds. But I’m starting to think I’ll toy with him when he goes down."
