In my opinion. If Pochettino in this match uses attacking tactics against Man City, perhaps the result will be different from your predictions, Man City could suffer defeat. Because in my opinion, if Pochettino applies defensive tactics, it will be the same as giving Man City an easy victory because we know they have many classy players. Apart from that, if Chelsea plays defensively then Man City will dominate the game and of course it will make Chelsea suffer, even the worst can be beaten with a large goal margin.
However, if Chelsea realizes this, it is very important for Pochettino to use an attacking strategy, be able to run and try as hard as he can. so this will also trouble Man City's defense. In essence, Chelsea must have the courage to challenge Man City if they want to win this match, otherwise Chelsea is ready to suffer defeat.
I think it would be less effective if Pochettino applied an offensive game play against Manchester City, it could actually provide an opportunity for Pep Guardiola to maximize the potential of Erling Haaland and also Kevin De Bruyne to score lots of goals if Chelsea dared to appear more aggressive. Manchester City difficult for build up their counter attack when opponent team make huge pressure but not prefer more offensive, just get counter attack when has good opportunity its better scheme for Pochettino if want take three points against Manchester City tomorrow match.
So far Pochettino scheme very risk when playing more offensive and many players left defense position and easily for premier league teams scoring goals against Chelsea, conceded 40 goals of 24 matches is very poor performance with Chelsea's defense and I don't sure they can't win against Manchester City if Pochettino use offensive games play.
