Messi would be the first to admit that he's failed to hit the dizzying heights of his club football over in the global arena, although Maradona's sudden outburst on "The Last Word Mexico" is more than a little harsh.
"We shouldn't deify Messi any longer", Maradona said in an interview with Fox Sports.
"We asked Guardiola to talk to [Messi]", Al Mubarak told a news conference in the United Arab Emirates, having identified the Barca star as the one player he wished he had signed.
Diego Maradona criticised Lionel Messi in a freaky interview in Mexico.
Maradona, who led Argentina to victory in the 1986, said Messi, who was again unable to emulate that feat in Russian Federation this summer was expected to be "the saviour of the fatherland".
"He is the best in the world along with Cristiano [Ronaldo]", Maradona said.
Maradona and Messi worked together during the former's ill-fated stint as coach of the Argentine national team between 2008 and 2010.
Interestingly, since Argentina's exit at the Mundial, Messi has blacked out Argentina games so far and no words yet when he return to action for the Albiceleste again.
Messi has been on the losing side in all four of his finals with Argentina - three in the Copa America and at the 2014 World Cup - and has not scored in four World Cup knockout stages.
And at the summer World Cup in Russian Federation, the South American nation failed to progress beyond the last 16 rounds after suffering a defeat against eventual champions France. "It's useless to try and make a leader out of someone that goes to the bathroom 20 times before a game". I don't know if we are ready.
"I come to Italy often, when I can, because I love this country", he said. We have to take the pressure off him. "If I have to decide for my team I will choose Messi over Ronaldo, three-time FIFA World Cup champion Pele said".
