Former IBF light-welterweight champion Paulie Malignaggi has told Amir Khan that he can forget about facing Floyd Mayweather.
The 25-year-old was knocked down three times as he went on to lose to Danny Garcia by TKO on Saturday in Las Vegas.
The Brit had previously claimed that he was ready to take on Mayweather, although Malignaggi believes that Khan won't have that chance.
Malignaggi wrote in his BBC Sport column: "The next few days will be tough for Amir. The media is so fickle. One day you're on top, the next you're not and you're being trashed. Two years ago I was written off and now I'm a world champion. Amir will be written off and people will say he can't hack it. There will be a lot of people with all the answers.
"But Amir's going to have to have the mental strength to deal with this and to believe he can come back from it, because most people aren't going to believe he can do it.
"One thing I am sure of is that Amir can forget about Floyd Mayweather.
Mayweather will probably be retired in a couple of years when Amir might be ready to take him on, so this loss means he has lost that fight."
Mayweather is currently serving a 90-day prison sentence.
