Dani Alves has slammed Alan Shearer's 'idiotic' criticism of Brazil striker Fred.
An early favourite to land the World Cup golden boot, Fred has underwhelmed, failing to score in two Group A matches, while appearing to dive for a penalty in the hosts' opener.
And Shearer accused the Fluminense forward of damaging Brazil's chances of winning the World Cup on home soil.
Speaking after the Samba Boys' disappointing 0-0 draw with Mexico in Fortaleza, the former England captain said: "(Fred) doesn't move, he doesn't shoot and he's dragging the team down."
But the Barcelona defender said Shearer, who has experienced the heat of World Cup battle first hand, should be ashamed of his disrespectful remarks.

"Those comments are some of the most idiotic that anyone can ever say," Alves told reporters just outside Rio de Janeiro.
"Someone who played football, who knows how difficult it is to be a football player, how difficult it is to beat opponents, compete, score goals, it's a shame for football and a lack of respect for his colleagues that play the game. It's something to be ashamed of."
Brazil will look to book their spot in the knockout stage when they face Cameroon in Recife on Monday evening.
