Chelsea played well in the recent two games they had first in Premier League they beat Leeds and got an important three points which had a good effect o the atmosphere of the team and then when everyone including myself was thinking they will lose the game against Dortmund the won the game with a 2-0 result but still they are 10th of the table and they got only 34 points that's why they have a long way to reach the top teams in the league.
I think this two recent games of chelsea are their best game they have performed so well for the season. The improvement of Chelsea is a good development despite the season has gone so far. If Chelsea continues end up with good result in every game it is a good improvement against next season and will definitely make Graham Potter to last as Chelsea coach. If Chelsea succeed in defeating Tottenham in their next game then it is an evidence that their performance is stable.
