No one really expected Chelsea to return to the top four in such a short time after they replaced most of their players with new players. They have renovated their squad on a large scale and they have spent billions of dollars on it, but still Pochettino needs time to get the best form from his team.
Of course this will not be easy because every player has a different time and way in the adaptation process, but if Pochettino is really able to make these players bring out their best potential then I think it will be difficult to beat Chelsea in the future. For this season, Chelsea is not a strong team compared to Liverpool or Manchester United, but they have the opportunity to develop rapidly over time.
That's right, the opportunity for a club as big as Chelsea is always there, even though I'm still not sure about Chelsea's current results, that's okay. There is still time to develop and find his game again. However, it cannot be denied that other clubs besides Chelsea have developed earlier. Let Pochettino do his job, because apart from player support he must also be given full trust by Chelsea owners in rearranging and selecting his players.
Then to be able to see Chelsea's stability we need to wait until mid-season. So it can be a consideration whether or not Pochettino is suitable for the players he brings in. In my opinion, this season Chelsea can still compete with Manchester United. The reason is simple because the characteristics of Chelsea players are far more manageable than Manchester United.
