United 'ask' about Ronaldo availability - reports

Former Manchester United striker Cristiano Ronaldo wants to return to Old Trafford for Rio Ferdinand's testimonial next year, according to The Sun.

The 33-year-old will celebrate 10 years at United next year.

After Ronaldo missed Paul Scholes' and Gary Neville's testimonials earlier this year, the Portuguese star is reportedly eager to make it this time around.

He also was absent for Sir Alex Ferguson's 25th anniversary as United manager.

Reports suggest both United and Madrid are already in talks about Ronaldo's availability next summer, which could include a number of events to mark Ferdinand's ten years.

Ronald is high on United's list, but no date will be set until after Euro 2012 and the summer Olympics.
