Graham Potter is able to change Chelsea's gameplay very quickly. Chelsea had a strong squad. However, their performances have been very poor since the start of this season. Chelsea dropped points in the first two matches of the Champions League. But their performance in the last match was very organized. Chelsea are stabilizing themselves very quickly. Graham Potter is doing a great job.
That's to show you that Chelsea weren't lacking players but the players were tired of playing for Thomas Tuchel and yet many fans were criticizing the owner for sacking him. If you watched Chelsea gameplay prior to the sack of Thomas Tuchel, you would had noticed how poorly the guys were playing. Nobody was interested in shooting at the goal post. All they do is pass the ball around until the opponent gets a break and score then you begin to see the players try to get and equalizer to draw the game at most. Thomas also had one attributes that disgust me which was playing players out of position.
This was one of the reasons players were becoming tired of his style of play. Sadly we have let go of some good players that won us the champions league due to Thomas Tuchel not having good game management. Potter is changing all that and the world shoudn't be surprised when we lift a silverware this season as that has always been the culture of the club, winning trophies.
