City are reportedly said to be plotting a world-record move to bring the Argentine to English football as he is considering a new challenge at the end of his contract this season at Barcelona.
According to Metro.co.uk, the 250 million-pound deal would comfortable make Messi, who is enduring a frustrating season with Barcelona, the most expensive footballer of all time.
However, it is yet unclear if Barca would reportedly consider selling their prize asset despite dragging negotiations over a contract extension for Messi to stay at the Nou Camp.
Messi would be reportedly handed a giant salary if he moves to the Etihad Stadium, which is speculated to be more than the 3,00,000 pounds-a-week, which Wayne Rooney currently takes home at Manchester United.
Despite Barca's uncertainty over selling Messi, given a forthcoming transfer ban that would not allow them to buy a replacement, City are confident that Argentine international wants out of the club, the report added. (ANI )
