Manchester City boss Manuel Pellegrini is convinced they have the rest of Europe rattled.
Pellegrini says no-one will relish playing his free-scoring side, who have banged in 15 goals in their five games in Group D following their 4-2 victory over Viktoria Plzen.
"Spain has strong teams, Barcelona and Real Madrid especially, but also Atletico Madrid are having a very good season," he said.
"But I'm not afraid of who we are going to play in the next round. It's not a major problem. Anything can happen in two games. We have a strong squad.
"People might say it's difficult for us to play against Barcelona, Real Madrid, Atletico - or Paris Saint-Germain are another team we could face.
"But all of them would not be happy to play against us."
