Manny Pacquiao believes Conor McGregor will have to "rumble" Floyd Mayweather in order to beat the undefeated star.
Mayweather and McGregor meet in Las Vegas in just 10 days time, with Mayweather coming out of a two-year retirement to make the fight.
His penultimate fight was against Pacquiao, and the Filipino says that McGregor doesn't have what it takes to land a meaningful punch on 'Money', adding that the UFC star needs to "get lucky".
Mayweather recorded a landslide unanimous decision victory over Pacquiao in 2015, in what was branded the "fight of the century" in the build-up to the bout.
The result settled the score over who was the best in the world, and Mayweather went on to record another unanimous win over Andre Berto to make his record 49-0 before retirement.
And, when the eight-weight world champion was asked about the upcoming fight, Pacquiao was very blunt about the Irishman's chances.
"McGregor has no chance in this fight," he stated.
"The guys who caught him and rumbled did best.
"McGregor is of that school. Maybe he'll get lucky."
Having been in the ring with Mayweather, the Filipino debated whether McGregor has the necessary professional experience to put up a challenge in Las Vegas, with this being his first professional boxing match.
'Notorious' is undoubtedly the most well-known star in the UFC today, though, and he recorded a stunning 13-second knockout over Jose Aldo in December 2015, which prompted his rise to stardom.
However, Pacquiao believes he has bitten off more than he can chew this time.
"There is no way he will be able to land a meaningful punch on Floyd," added Pacquiao.
"How could he? He (McGregor) has no professional experience in boxing."
Despite the lack of experience in the ring, Notorious does have one thing, and that is self belief. No matter what the neutrals are saying, the Irishman will back himself on August 26.
Whether that's enough, remains to be seen.
