Cristiano Ronaldo believes his Manchester United side are a 'better team' than Internazionale.
The Portugal winger is expected to be one of the key protagonists when the two sides go head-to-head in the last 16 of the Champions League on Tuesday.
But ahead of the first leg, the Portugal winger has warned Inter that they are poised to come up against a side which is currently at the top of its game.
"It's time to kill or be killed," Ronaldo told uefa.com. "Whoever loses will exit the competition and we don't want to lose, we don't want to get stuck along the way.
"It will be a difficult game, but I think that Manchester United have a better team and we'll do our best to win it.
"They're (Inter) a team we need to respect. They're a good side and first in Serie A so we need to be very careful.
"They're a team with very experienced players, but we also have our aces and great players. We have a more experienced team, we're the reigning champions.
"It will be a good game, a well-contested game, and the better team will win."
