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.
Don't you think it's a little early to draw that conclusion? Pochettino, in my opinion, is still in the squad-building stage, even if he doesn't have all the time for it right now because time is not on anyone's side if he wants to end well this season. Chelsea have not been playing particularly poorly in terms of football performance; what they need is the ability to blend together, understand each other, and utilise this to their advantage in winning games. I don't think there's a position where they don't have a good or even an average player, that they can’t win matches.
