Manny Pacquiao has become the latest man to challenge Conor McGregor.

After being defeated by Floyd Mayweather in his debut boxing bout earlier this year, Conor McGregor's next move has become one of the most discussed topics in all of sport and now, another option has come to the fore.

While fights with Nate Diaz, Tony Ferguson, Paulie Malignaggi and Oscar De La Hoya have all been rumoured, Manny Pacquiao has thrown his hat in the ring with a rather surprising Instagram post.

Manny Pacquaio told McGregor to "stay fit".

Happy Thanksgiving! Stay fit my friend. #realboxingmatch #2018 @thenotoriousmma

The legendary Filipino fighter – who previously stepped inside the ring with Mayweather in 2015 – has seemingly declared an interest in challenging McGregor, telling the Irishman to "stay fit my friend" for a "#realboxingmatch" in 2018.

This is another fight that looks unlikely but given Pacquiao's profile, it could be the biggest money fight on offer for McGregor next year.

We all know that money talks.
