"Manchester City are one of the best teams in Europe, if not the world, to watch at the moment", Mills told Sky Sports News.
City face Shakhtar Donetsk in the Champions League on Wednesday, but having already secured top spot in their group, there is little riding on the game.
Pogba will miss the Manchester derby for this tackle.
"If City were to win this, are they uncatchable?"
Shakhtar started aggressively and took the lead in the 26th minute when Bernard cut in from the left side of the box and curled a shot inside the far post, beyond the reach of goalkeeper Ederson.
"Against Arsenal, they could get away with it". City also returned to the 3-4-3 formation that looked less than fluid in the first few games of the season. Phil Foden showed good composure although this was a tough test for the 17-year-old in an unfamiliar wing back role.

"Hopefully, we can win the game, that would be massive". Brahim and Foden are City's two brightest youth prospects and any first-team opportunities can not be taken for granted. Those preparations will start before City even leave Ukraine.
City will train again back in Manchester on Friday afternoon and by kick-off on Sunday the vast majority of their strongest XI will have benefited from a midweek rest.
He declared: "For players like me and Vinnie (Kompany), the older players, and we see the younger players like Sane and Sterling coming in. we play with more confidence".
City midfielder Bernardo Silva said: "The game didn't go as we expected, in the first half they were better than us and it was a deserved win for them". That is nine of 10 outfielders who have hardly been overworked of late.
"It means a lot to everyone. but you've got to play with your heads and if you're going to go blow-for-blow with Manchester City with attractive football, then I think you're going to come unstuck".
A win will see City break a Premier League record for most consecutive wins while at the same time shatter United's unbeaten record at home - which will stretch to 40 in all competitions if they avoid a loss to CSKA Moscow on Tuesday [5 December] night.More news: John Mayer Has Been Hospitalized To Undergo An Emergency Appendectomy
