Nani has defended former Manchester United teammate Cristiano Ronaldo over this week's behaviour.

Ronaldo has been dropped and banished from senior training after leaving victory over Tottenham before the final whistle while being an unused sub.

Nani, now with Melbourne Victory, said: "I didn't see that situation, I don't know what happened, but maybe he needed go to the bathroom.

"Everyone knows that Cristiano is a great professional, he works hard to play and maybe he is frustrated because he doesn't play ... "
