Milner hit the winner at Champions League opponents Bayern Munich on Tuesday night.
He said: "We'll take anyone. We will just concentrate on us.
"It's going to be a tough team whoever we get, but we'll take confidence from this and know we can progress.
"It couldn't be tougher than Bayern. They are the reigning champions and I think they have been to three finals in the last four years, or something ridiculous like that.
"They're obviously one of the top teams and have been the last few years, so to be able to come here and win is pleasing.
"Hopefully it shows the quality we have and gives us a big confidence boost going forward."
