And while we'd certainly love to see him playing in the Premier League, City striker and Messi's worldwide teammate Sergio Aguero believes the chances are fairly low.
Fresh off netting a hat-trick against Ecuador earlier in the week to help Argentina book their place at next summer's World Cup, Messi will now turn his attentions to Barca's important La Liga clash with Atletico Madrid at the weekend.
"The money isn't a problem here [at City]", Aguero told Argentine channel TyC Sports.
"But Leo, just like other players like Ronaldo, are symbols of their clubs and it's hard to leave not just to City but to other clubs that also have the money".
"I would love to have Leo on my team, but that seems quite complicated".
Aguero is on the sidelines after breaking a rib in a auto crash in Amsterdam at the end of September, an injury which kept him out of Argentina's final two World Cup qualifiers and was expected to prevent him from playing throughout the rest of October.
The 29-year-old traveled to the Netherlands on a day off but was involved in an accident as a passenger. I'm lucky to know Maluma's agent and he invited me to his concert, which I went to. I had nearly two days off and going to the airport was when I had that accident.
"But he's a symbol of his club and I think it would be rather hard".
"Today I have trained normally, but not yet with the group. (On Thursday) I'll rejoin the group and see how I feel, whether I'm comfortable or not".
