Brazil have demanded greater protection for their artists from World Cup assassins.

Midfield star Elano became the five-time champions' latest injury casualty when the Galatasary player, who has scored twice in the tournament, was rated as doubtful for the quarter-final against the Netherlands on Friday (Saturday AEST).

Elano picked up an ankle injury in the group match win over Ivory Coast and he subsequently missed the scoreless draw with Portugal and Monday's 3-0 round-of-16 win over Chile.

"I didn't get the chance to speak to the referee (after the incident against the Ivory Coast), but he didn't even whistle for a foul," Elano said.

"There was a foul on Robinho later that should really have merited a red card.

The referee for that match, Stephane Lannoy awarded a drop-ball instead.

"We have various characteristics in our squad, but there is no one who goes out there with the intention of injuring an opponent.

"The problem is that it's me who pays the price because I can't be available for my team. These fouls must be punished."

Brazil coach Dunga also believes his players are not being protected sufficiently and was angry that Kaka was yellow-carded in the 3-0 last 16 win over Chile on Tuesday.

"The technical players are punished and those who commit the fouls are not. It's pathetic," said Dunga.

Central defender Juan, who earns his living playing with Roma in the rough and tumble of Serie A, believes players like Elano are deliberately targeted.

"I deeply regret that a professional footballer goes on to the pitch with the intention of injuring a player as was the case with Elano," said Juan.

"I think teams have to play hard against Brazil because they know that Brazil know how to play football and when we play a little tougher, we are carded."
