Who knows how many matches Pochettino needs to increase his players' confidence to be able to win matches, but they have failed in 5 of the first 6 matches this season. I won't completely say Pochettino will fail this season with Chelsea, but I can really predict that his work for Chelsea this season will be very tough.
He's already failed to create a new Chelsea, there's no need to wait anymore as the result will be pretty much similar like the present.
Chelsea will not able to reach top 7 positions, but they're not really as bad as weak teams in relegation zone, at least Chelsea is safe and not relegated to Championship league.
Chelsea must sack Pochettino ASAP before they suffer larger loses.
It is possible that Pochettino will be fired in the near future, it could be said that he has failed in managing the Blues squad this season. Chelsea performance is worse than Manchester United, and is now in 14th position at the bottom of the standings. Yes, if you continue to rely on young players with little experience in the string XI, the results will still be the same. To be relegated I think the same, this will not happen. The players are also responsible for the decline in team performance, they must show a contribution commensurate with their value.
Playing at home should be able to be put to good use even though several key players are injured, because Pochettino back-up players are still better than Aston Villa main squad. The next match they played in the Carabao Cup against Brighton, we know that Brighton this season has beaten Newcastle and Manchester United. The Blues will face a difficult opponent, Pochettino must be able to lead Chelsea to victory if he doesn't want to be fired before the season ends.
