I don't spit on the plate from which I eat," Real Madrid striker Cristiano Ronaldo said here when asked about Blancos ex-coach Jose Mourinho's having compared him unfavorably with retired Brazilian star Ronaldo.

"Some things in life are not worth commenting on and this is one more for obvious reasons," the Portuguese international told a press conference in Los Angeles, where Real Madrid is preparing for its final pre-season tune-up: a clash with Mourinho's Chelsea squad in the Guinness International Championship.

Mourinho, in a weekend interview with ESPN, recalled that during his time as an assistant with FC Barcelona, he coached Brazilian standouts Rivaldo and Ronaldo.

"The true Ronaldo, not the other one," the Portuguese manager said in an apparent jab at his countryman and former charge.

"I prefer to remember the good things from coaches. I don't spit on the plate from which I eat and I don't speak about people who say bad things about me," Cristiano Ronaldo said of Mourinho.

"We are going to face Chelsea, not their coach. It is another warm-up game and we hope to win it so we can start La Liga in the best manner possible," CR7 said.

Real Madrid has won all of its pre-season matches so far under Carlo Ancelotti, the successor to Mourinho, whose three-year tenure with the Blancos was marked by disappointment.

CR7, a World Player of the Year, said he has still not signed a contract extension with Real Madrid.

"I am happy here and all I want to do is train and prepare well," he said. "The contract renewal hasn't been resolved yet, but I shouldn't talk about it because it isn't the right moment." EFE
