Van Heerden's tweet goes viral

But one man who thinks McGregor stands no chance is the Irishman’s former boxing sparring partner, Chris van Heerden.

The 29-year-old former IBO welterweight champion has posted footage of himself and McGregor sparring alongside the caption: “People telling me Mayweather will have his hands full trying to land on McGregor -STOP IT! I respect McGregor BUT i ain't Floyd and i landed”.

The tweet, posted on Wednesday, has been retweeted over 7,000 times and received a similar number of ‘likes’.

He then tweeted again on Friday.

The South African added: “The 1's hating on me REMEMBER Conor's team released edit footage FIRST they leaked it! What i do now is standing up for boxing/boxers #fair”.

McGregor has his work cut out

Based on the footage, McGregor will have his work cut out against Mayweather, who is confident of securing the 50th and final victory of his illustrious career.

Maybe he’ll surprise us all on the night - but we’re not banking on it.
