Chelsea are doing much better than bottom of the table teams. Their level hasn't stooped so low that they will be relegated so easily. They have lot of good players in squad and I think they have lot of potential to get back on track again. The team chemistry is just not upto the level that a big 6 team should have inn Premier League. Yeah they also need to make some good signings in area where they lack, for instance on defence (particularly centre back).
Chelsea performance are merely classified as mediocre this season. I've seen no quality performance from Chelsea this season, I'm still watching the exact Chelsea game pattern under Frank Lampard and Graham Potter. When Todd Boehly appointed Mauricio Pochettino as headcoach, I thought everything will work out fine and smooth for the club, but it will definitely take time before this event could be triggered. However, Mauricio Pochettino have intents for the club, he's keen on signing more players for the Blues this season and he will not hold back his determination and actions for his club.
