And Messi is torn over signing a new contract at the Nou Camp or beginning a new chapter in his career in Manchester.
Negotiations with Barca have been ongoing for 18 months but the deal remains unsigned.
City officials have met with Messi’s representatives on several occasions — making it clear they want him.
The 30-year-old is out of contract at Barca next summer and could sign for City in January and join for free in July.
City are understood to have offered a £40million signing-on fee and a five-year deal worth over £500,000 per week.
