Michael Carrick says any kicking of Manchester United teammate Cristiano Ronaldo simply acts as more inspiration for the Portuguese star.

"Cristiano is showing why he's such a good player. Some players have all the ability in the world but when they start to get kicked they fade out.

"What makes him so special is he is happy to come for more. He is world class and that is why he gets so much stick. He is really producing for us," said midfielder Carrick.
