Sir Alex Ferguson has told his Manchester United players not to fear the damage Cristiano Ronaldo can inflict on them before the Champions League tie against Real Madrid tonight, reports The Times. Tonight’s appearance at old Trafford will be Ronaldo’s first since he left United nearly four years ago in an £80 million deal. While joking that the best way to stop the Portugal forward was to hope that he failed to show up, the United manager told his players that worrying about him would only undermine their prospects of reaching the quarter-finals.
