Ronaldo is in fine form at present and Real Madrid will go to Old Trafford next Tuesday looking to win through to the last eight of the Champions League.

"United has a special place in his heart. The fans love him and it will be a great occasion. You enjoy going back [to your former club] and I am sure it will inspire him. Many things inspire great players and him going back will be a special night," said Beckham.

"United did very well at the Bernabéu. It will be a great game to watch. They are two great teams with great players, so it's difficult to call."
