In terms of motivation, chemistry and confidence, Chelsea have slumped from being the most disappointing team in the Premier League to simply being the worst. So far as Frank Lampard remains the coach of this Chelsea side, they’ll still not win any of their games. They have 5 more games to go. If Chelsea lose at the weekend they will find themselves below Bournemouth and possibly Wolves. And realistically, I don’t see them taking any point from the remaining teams.
Lampard's statistics in training Chelsea this time are 6 matches and 4 defeats for him with details of 4 in the EPL and 2 legs in the Champions League. Obviously this is not a good thing for them at the moment and I actually feel this is making Chelsea even worse at the moment.

They have 5 more games left for this season and as much as possible they should be able to get points against Bournemouth and Nottingham Forrest in order to secure their position a little in the mid-table because seeing the 3 final matches with Manchester City, Manchester United and Newcastle to be honest I doubt it.
If indeed they can secure 6 points in 2 matches out of 5, that is good enough because otherwise it is not impossible for them to continue to get closer to the relegation zone.
@CryptocurencyKing, After all, we can certainly say that it is not going to be surprising if Chelsea does not end up winning even a single match from those which are left. I don't think there is anything to achieve for Chelsea this season anymore. If they have a chance to win against any team in the upcoming matches, I will say it is going to be against Nottingham Forest. Otherwise, I don't see any team which will be an easy opponent for Chelsea.
Another thing is if Chelsea does win all of the five matches that are left, even that is not going to get them anywhere. Not even in the top six. They are certainly going to finish as a mid-table team.
