Amir Khan spent over a year lobbying for a fight against Floyd Mayweather before the U.S. boxer left the sport in September 2015.
And it doesn't look like Mayweather's retirement has dented the Bolton-born star's hopes of getting in the ring with his rival either, according to a video that has surfaced of the pair sat ringside for Saturday's Danny Garcia vs Robert Guerrero fight.
The footage shows Khan call out Mayweather but, despite the Brit's enthusiasm, the majority of boxing fans seem to think "Money" came away from their verbal bout with the victory. Scroll down this article to see the exchange.

As you'd expect with two athletes who, until recently, had been at the very top of their sport, neither Khan nor Mayweather were willing to back down during the argument.
As usual, though, the American had a couple of points to fall back on when Khan attempted to belittle him; his record and his money.
Getting the go-ahead
Just how serious Mayweather was, meanwhile, about returning in a couple of years to take on Khan is anyone's guess. The 38-year-old retired from boxing with a perfect 49-0 record, although many critics argued he avoided Khan in his last few bouts out of fear of losing the record.
You wouldn't put it past the veteran fighter coming back to the ring at some point, though, as so many of his peers have done in the past. If Khan continues to pester him at every fight he goes to, it might simply be a case of the U.S. boxer trying to shut his rival up.
