This is according to The Sun, who understand Messi is keen for his fellow Argentina international to quit Old Trafford for the Camp Nou this summer.
The report adds that Di Maria has asked his representatives to find him a route out of Manchester following an underwhelming debut season with the Red Devils, which saw him axed by Louis van Gaal during the second half of the campaign.
However, Manchester United have no interest in selling the versatile South American winger for less than the £59.7 million they paid for his services last summer.
This means Barcelona would need to submit a huge bid to even tempt United into offloading their record signing - the most expensive signing in British football history - while the fact Real Madrid inserted a clause stipulating £10 million be paid to them if he was sold to the Catalan giants would make the deal even more expensive for the reigning European champions.
Problems with the deal
There’s also the political issue about whether Barcelona would be prepared to sign a player who was effectively deemed surplus to requirements by their arch-rivals Real Madrid.
But Messi, who holds a lot of power at the Camp Nou - more so than Enrique himself if these latest reports are to be believed - clearly feels Di Maria would be an excellent addition to Barcelona’s treble-winning squad.
Another problem, though, is that Di Maria would be unable to play for Barcelona until January 2016 due to the club’s existing transfer ban.
While Barça are permitting to sign new players this summer - as they have already done so with Spain international Aleix Vidal - they cannot register them until the New Year.
Di Maria would struggle for starts at Barcelona
Furthermore, signing Di Maria would effectively rule Barcelona out of the running to sign their top transfer target - Juventus midfielder Paul Pogba - due to the astronomical potential cost of the two deals combined. Pogba, it’s understood, is keen to join Messi and co. at the Camp Nou.
And, finally, would Di Maria even start in Barcelona’s first team?
There’s an argument to suggest he would be a better option than Andres Iniesta in central midfield - the World Cup winner has not looked the same untouchable player since 2012 - but there’s no chance of him being selected over Neymar, Luis Suarez or Messi himself in the attacking positions.
With this in mind, it’s fair to say Messi should probably leave the club’s transfer business to Luis Enrique.
