Former Real Madrid manager Jose Mourinho has launched a jibe at Cristiano Ronaldo by claiming that the Portuguese star cannot handle criticism.

Mourinho, who was officially confirmed as the new Chelsea manager this week, has revealed that he encountered issues with Ronaldo during his three-year stint at the Bernabeu.

"I had only one problem with him, very simple, very basic, which was when a coach criticises a player from a tactical viewpoint trying to improve what in my view could have been improved," Mourinho told Spanish television show Punto Pelota.

"And at that moment he didn't take it very well because maybe he thinks he knows everything and the coach cannot help him to develop more."

Meanwhile, reports have claimed that Ronaldo has no interest in signing a new contract with Real when his current deal expires in 2015.
