The six-time Ballon d'Or winner is looking to call time on his Barcelona career after handing in a transfer request.
It follows a long season for the Argentine, which has just been one disaster after another.
Messi and the Barca board have collided over Antoine Griezmann, Ernesto Valverde and Neymar.
An 8-2 demolition from Bayern Munich in the Champions League has been the catalyst for a huge fallout which has seen the 33-year-old hand in a transfer request.
But now reports claim that Messi's father has been contacted by Juventus - opening the possibility of pairing Ronaldo and Messi together.
It would give football fans the chance to witness something that has always preyed on minds.
What would a team look like with both Messi and Ronaldo in it?
The Portuguese legend made the move to Turin in 2018 after his own fallout with Real Madrid chiefs.
Since then, the forward has continued his goalscoring exploits - netting 65 in 89 appearances for the Bianconeri.
Ronaldo and Messi pairing up together at the top of the pitch would certainly be an interesting proposition.
But it is already a summer of change at Juve after sacking Maurizio Sarri and hiring Andrea Pirlo.
The Serie A champions are perennial winners in the league but they are desperate to transform that success on a European basis.
Ronaldo was brought in to help win the Champions League but he is yet to taste victory there in two seasons.
Messi, at 33, is no different - hellbent on landing the trophy before the end of his career.
It could see the two footballing legends put aside their rivalry in a bid to form one of the most incredible partnerships the sport has ever seen.
Ronaldo scored 37 times last season while Messi netted 31 - which, incredibly, are relatively low-scoring campaigns for the duo.

The pair have been the undisputed kings of football for the last decade but have always been opponents.
Surely with the duo on the same team, that strike force would inflict fear on any defence in the world.
Juve potential starting XI: Szczesny; Danilo, De Ligt, Bonucci, Sandro; Rabiot, Arthur, Ramsey; Messi, Ronaldo, Dybala.
