Real Madrid striker Ronaldo defended his former coach Vanderlei Luxemburgo and said the players, including him, were responsible for the recent disappointing results.

"We (the players) are guilty," Spanish paper Marca quoted Ronaldo as saying in an interview with Brazil's radio station Globo.

"We were not able to apply Luxemburgo's strategies onto the pitch, so we couldn't achieve positive results."

Real Madrid sacked Luxemburgo earlier in December after the team slumped to fifth spot in the Liga standings, 11 points adrift of leaders and arch-rivals Barcelona.

Ronaldo is on a vacation in his homeland where he revealed his hopes of breaking the World Cup scoring record in Germany 2006.

"I hope I can score more goals in the World Cup to break the current record. This is my objective," Ronaldo said.

Registering 12 times so far in two World Cup events, the 29-year-old is just two goals away from all-time scorer and German legend Gerd Muller.

"This will be a unique opportunity to write my name in football history and set a record that would be difficult to break in the future," he added.
