Maybe he is finally getting the team together and understanding the players better or maybe they are just luckier in the champions league than they have been in the premier league. Until the end of the game, I was not convinced that Chelsea were going to finish off well. They had many opportunities that they would have been able to score more than just two goals, luckily for them they did not concede plenty goals when they played away to Dortmund in the first leg. This victory gives Graham Potter some fresh air from the series of losses he has recorded as a coach with Chelsea.
