According to The Sun, Diego Maradona is a bit of a Grumpy Gus today after being told that he won't be allowed to go and meet his favourite cartoon friends at Disney World after U.S. authorities refused to grant him a Visa.Maradona had booked a family trip to the Florida theme park for his girlfriend, his daughter and his ever-swelling clan of grandchildren, but was denied entry to North America due to his well-publicised friendships with so-called "enemies of the USA".Apparently, the Argentinian legend -- currently between jobs having been sacked by Al Wasl last summer -- pleaded his case in person at the US embassy in Dubai, but his Visa application was still refused, with a source informing The Sun that the decision was "political", telling the tabloid:“[Maradona's] relationship with the U.S. has never been good. His friendships with Fidel Castro and Hugo Chavez and other enemies of the US stopped him being given permission before."It was a bit of a kick in the teeth for Diego. The family were really excited about the holiday."So unfortunately there'll be no photograph of Diego out of his mind with happiness while posing with Goofy, just like when Mario Balotelli got to meet a certain sponge who lives in a pineapple under the sea.
