Manchester United boss Sir Alex Ferguson has branded Manchester City's interest in Cristiano Ronaldo as "absurd".
Ferguson said: "There's plenty of talk from them. They spoke about trying to get Cristiano Ronaldo, which is absurd.
"The great thing about my time here is there has always been a challenge.
"What you see of Manchester United today is not an overnight situation.
"This club has been built up over years. We'll be here for a long time no matter where the challenges come from."
