Jose Mourinho has taken a stinging potshot at ‘know-it-all’ Cristiano Ronaldo following their Real Madrid divorce.Mourinho spent three years working with £80million Ronaldo before this week quitting Spain to take the Chelsea boss job.The Portugal star scored 165 times under the Special One and Mourinho insists it was HIS tactics that sparked Ronaldo’s astonishing goal spree. And the former Porto boss has revealed how he clashed with Ronaldo because the forward was too precious to take criticism.Mourinho said: “He had three great seasons with me, I don’t know if they were the best in his career because at Manchester United he had great seasons too.“But I think we found for him a tactical situation that helped him express himself on the pitch perfectly as shown by goal figures.“The only problem has been that a coach criticises him from a tactical point of view trying to improve him and he has not accepted it well thinking, perhaps, that he knows it all and that the coach could not help him become any better.“But there is no other problem.” SunSport today revealed how Ronaldo, 28, is closing on a sensational £65million move back to Manchester United.He only has two years left on his current deal and is refusing to open talks about a new contract.The strike star missed the final two games of last season — but Mourinho says Ron was NOT trying to force his way out of the Bernabeu.The new Stamford Bridge chief said: “The last two games, which have been the only games in which he has not played because he always played before and he always gave everything for the team... in these last couple of weeks he has had this pain in his back and I don’t ever doubt the players when they say they are injured.”
