London, Feb 24 : Manchester United winger Cristiano Ronaldo reckons that it is time to "kill or be killed" in the Champions League.

The Portuguese superstar predicts Manchester United will deal the fatal blow to Inter Milan when they clash in the San Siro tonight.

"We have a more experienced team and are the reigning champions. It's time to kill or be killed. Whoever loses will exit the competition - and we don't want to lose," The Sun quoted Ronaldo, as saying.

"It will be a difficult game but I think Manchester United have a better team. They're a team with very experienced players but we also have our aces and great players.

"It will be a good game, a well-contested game, and the better team will triumph. I have won the Champions League and want to repeat that very soon," he added.

Meanwhile, manager Alex Ferguson insists the players will stand up to the tackles by Inter Milan players.

"When we came here two years ago and played AC Milan in the semi-final, we saw the immaturity of the boy. But he is a different player now. I want to see maturity from Ronaldo and everyone else because of the atmosphere and the competition," Ferguson said. (ANI)
