Ferdinand fearful of Ronaldo exit

Manchester United winger Cristiano Ronaldo's apparent 'come-and-get-me' plea to Real Madrid has left Rio Ferdinand fearing for the future of the Old Trafford side.

The 23-year-old, currently preparing for Euro 2008 with the Portugal squad in Switzerland, scored 42 goals for the Premier League and European champions last season - and is widely considered the best player in the world on current form.
