Floyd Mayweather calls Conor McGregor ‘extremely dirty and illegal’ ahead of mega-fight

Undefeated  boxing champion, Floyd Mayweather, has come out to criticize Irish UFC champion, Conor McGregor, claiming the boxer is extremely dirty and performs illegal boxing techniques. 

Mayweather called out McGregor after seeing video clips of a sparring session between Conor and former world champion, Paulie Malignaggi.

Many boxing observers believe Conor McGregor, 29, has age on his side and could use it to his advantage against Mayweather, 40, who has been out of professional boxing since May 2015, having previously retired from the game.

In the mega fight set to hold in Las Vegas on August 26th, McGregor will have to avoid using his legs and fight Mayweather with his hands only.

The footage gave Mayweather an insight into the boxing skills of McGregor, who has a tendency to try 'a lot of grappling, a lot of wrestling, (and) a lot of illegal shots'.

But McGregor, a two-weight UFC champion who has previously claimed he would beat Mayweather inside four rounds, remains confident he can shock the world.

I have a game plan and I will execute it perfectly, like always, he said at a media workout in Las Vegas.
