Taking to Twitter, he wrote: "Here’s an idea for you guys... the Nba has all-star game! Don’t you guys think we should organise one in the Premier League... The north vs the south! And the fans vote... what do you guys think?"
But what would the teams look like should an all-star game be played right now?
We've had a go at picking the XIs for both the north and the south. View them below...
North XI (4-3-3)
GK: Alisson RB: Trent Alexander-Arnold CB: Virgil van Dijk CB: Ruben Dias LB: Joao Cancelo CDM: Fabinho CM: Kevin De Bruyne CM: Bruno Fernandes RW: Mohamed Salah LW: Sadio Mane ST: Cristiano Ronaldo
Subs: Ederson, Kyle Walker, Raphael Varane, Andy Robertson, Rodri, Phil Foden, Jack Grealish, Roberto Firmino, Jamie Vardy
Manager: Jurgen Klopp
South XI (4-4-2)
GK: Edouard Mendy RB: Reece James CB: Antonio Rudiger CB: Thiago Silva LB: Ben Chilwell CM: Declan Rice CM: N'Golo Kante LM: Heung-min Son, RM: Bukayo Saka ST: Harry Kane ST: Romelu Lukaku
Subs: Aaron Ramsdale, Cesar Azpilicueta, Ben White, Vladimír Coufal, Jorginho, Matteo Kovacic, Mason Mount, Pierre-Emerick Aubameyang, Michail Antonio
Manager: Thomas Tuchel
So, which team would win? Both sides are stacked with talent but it's hard to pick against the north XI.
The fact that players including Robertson, Foden and Grealish won't even make the best XI just goes to show how strong the side is.

But, on paper, the south XI doesn't quite have the same star power as the north XI.
That doesn't necessarily mean they will come up on the losing side, though.
An all-star game would be a fascinating watch and we would be more than happy to see Lukaku's idea come to fruition.
