Messi shocked Barca on Tuesday when he informed the team of his intention to leave this summer, despite having a contract until 2021. Barca responded by asking him to stay at the club he first joined as a teenager almost 20 years ago.
The two spent four years together at Barca between 2008 and 2012, and the Man City coach spoke to the Argentina international about the project that awaits him in England if he decides to make the move.
Messi hopes to execute a clause written into his current terms, signed in 2017, that allows him to leave for free, unilaterally, at the end of each season. Barcelona earlier this year, say the clause expired in June.
Paris Saint-Germain coach Thomas Tuchel said this week that Messi would be "welcome" at the French champions, and other clubs are expected to move for the six-time World Player of the Year if he is able to force an exit for free.
