Diaz, 34, shared twelve rounds with Khan the last time the Briton fought, dropping him and giving as good as he got in an entertaining Sheffield clash, with some raising an eyebrow or two at the close unanimous decision handed to the home fighter at the end.
The Californian-based Mexican was surprised himself to hear that the Olympic silver medallist is the likely contender to oppose Mayweather in his 46th pro bout at the MGM Grand and sees a couple of Khan’s old rivals as better choices.
“I know that business speaking Floyd Mayweather fighting Amir Khan might make sense because the fight can generate a lot of UK sales, but I personally don’t think Khan has done anything to earn that spot,” Diaz exculsively told World Boxing News.
“I mean, Khan couldn’t even get past an older fighter like me who is considered washed up. But oh well, that’s the sport. I think a fight for Floyd against Marcos Maidana or Danny Garcia would make more sense to the fans, but that is just my view.”
If the fight is rubberstamped in the coming weeks, by the time Khan enters the ring to face Mayweather he would have been out of the ring some eleven months since that tight victory over Diaz last year.
It can’t be ideal preparation for the Bolton fighter, who fought Diaz at a catchweight of 142lbs and is yet to fully test the waters at welterweight since announcing his decision to leave his successful stint at 140lbs behind.
Maidana has now dropped out of the race due to his impending rematch with Adrien Broner which was confirmed to WBN by Richard Schaefer for April this week, whilst Garcia has apparently never been considered by The Money Team.
