Former Manchester United defender Rafael has insisted that his ex-teammate Anderson could have been "the best in the world" if he did not eat so much McDonald's.
The Brazilian fullback has claimed in his joint autobiography with twin brother Fabio, called The Sunshine Kids, that his fellow countryman's fitness and weight problems were exacerbated by his love for fast food.
The Red Devils paid £28 million (R556 million) to sign Anderson from FC Porto in 2007, and he went on to play a big part in one of the club's most successful squads in history, and also won the 2008 Golden Boy award after some impressive performances for United.
However, many feel he never lived up to his full potential, and his ex-colleague Rafael has now insisted that, had the Brazilian midfielder been more "professional", he could have been the best player in the game.
"We could be on the team coach and pass the services on the motorway and Anderson would jump up impulsively and yell 'McDonald's, McDonald's'," an excerpt from his autobiography reads, according to the Daily Mirror.
"The guy was crazy, but I love him. Give him a football and he would just play with freedom and sometimes, if he got a good run of games, he could play as well as any player in the league.
"Not only that, but when he was playing well, we were playing brilliant football. He picked up a lot of big injuries and then his problems with eating the way he did started to affect him.
"It was no coincidence that his best form came when he had a lot of games because that was when he couldn't eat so much.
"I will say something about Anderson – if he had been a professional football player, he could have been the best in the world.
"I'm saying this with all seriousness. I don't know if he ever took anything seriously. He just loved life in such an easy and casual way. In some ways, that was a quality. It was what made him so popular and one of the most popular players at the club.
"But he would just eat whatever was put in front of him."
