City were the favourites to sign Messi last summer before he eventually decided to remain at the Catalan outfit. Messi will be in a position to leave the club for free next summer, when his contract expires. If he decides to leave the club, he will surely attract interest from a number of clubs, including City.
However, City could make a move for the Argentine even before next summer. According to Daily Star, the Cityzens could offer Barcelona £15m in the January transfer window, which would likely put them ahead of the race for the six-time Ballon d'Or winner.
However, it remains to be seen what Messi decides regarding his future. Only time will tell what he decides: whether to extend his contract with the club or leave for free at the end of the season.
Meanwhile, Messi's focus now will be on helping Barcelona in the 20-21 campaign. The Catalans succumbed to their first defeat of the new season in their recent fixture, as Getafe inflicted a 1-0 defeat in the league match. Barca had the change to go top of the points table with a win against Getafe, but the defeat sees them sit ninth in the points table.
