Marcos Maidana, 31, pushed 37-year-old Floyd Mayweather all the way in their first meeting in May with the American claiming a majority points win.
But as they prepare to square off again in Las Vegas, Maidana's former foe - Amir Khan - had some words of advice for the man he beat in 2010.
The Bolton fighter, who will be ringside in the early hours of Sunday morning, said: "I really believe speed is one of the key components in beating Floyd.
"Speed of hand and speed of foot - even speed of mind.
"It's not the only thing but it's very important, as is having a good jab and being able to answer the questions he poses.
"You can't be one dimensional against Floyd because over and over in his career he has shown that he makes changes to whatever style his opponent comes with.
"Yet, when you look at it, up until Maidana the people who have troubled him the most have been people with speed and good movement, those are things I possess.
"Maidana made it a very rough and rugged first fight and showed Floyd no respect.
"That was his game plan, to go in there and treat him like he was a nobody and in a way it definitely worked for him because he gave Floyd a tough fight especially in the early half of the fight.
"But against Floyd you can't go in there with one strategy and think it's going to see you through the fight because he is very clever, very smart and makes adjustments."
Khan will not make the trip to Vegas as a Visa mix-up has prevented him from boarding a fight to the USA.
But the 27-year- old main ambition is to be in the ring, not front row, with Mayweather next year given he hopes to be picked as an opponent by the five-weight world champion for one of his two remaining outings.
Khan, 27, has his own ambitions of facing Mayweather next year and remains hopeful the five-weight world champion will give him a shot in one of his two remaining outings.
Mayweather, who defends his WBA and WBC welterweight titles and WBC light-middleweight belt against Maidana, revealed earlier this week he will retire next September.
Khan said: "It's a fight that many want to see happen just because our styles would make a very interesting clash.
"If I keep winning then I think it's a fight that could definitely happen in the future.
"Floyd has said the same thing to me in the past.
"For now, I'm out again in December so I'm looking to get my opponent named for that and putting on a great performance in my next fight.
"But if it makes sense for both sides then it will be a fight that could happen.
"I don't want to put a timescale on it but I got into this sport to fight the best and at the moment Floyd is ahead of everyone so it would be great to test myself against him."
Khan is not concerned that Maidana could scupper those hopes this weekend by ending Mayweather's 46-fight unbeaten record.
He added: "I think this fight Floyd will be a lot more composed this time and will know what he's getting when he faces Maidana.
"I think Floyd is going to be smart, box from the outside and maybe leave Maidana chasing his shadow."
