Manchester United ace Cristiano Ronaldo says it will be "killed or be killed" tonight against Champions League rivals Inter Milan. Ronaldo said: "They are a team we have to respect. They are a very good side who lead the Italian league by a lot of points so we must be very careful.

"It's time to kill - or be killed."

The World Player of the Year said: "The feeling of the Champions League is unique.

"When you hear the music and you come out onto the pitch it's a completely different game and atmosphere to the others.

"The emotion of winning my first Champions League medal was spectacular. When [Edwin] van der Sar stopped [Nicolas] Anelka's penalty it was like the earth stood still.

"I hope to repeat that feeling very soon."
