Chelsea's victory over Dortmund was deserved by them because from an executor's point of view, Chelsea has many choices of players who can do it. What's more, Sterling's performance is clearly the key to this success. He is able to open up a lot of space to create goals. Havertz once again if the penalty is not repeated then as usual he will always perform badly, but this time he was quite lucky.
Dortmund were unable to react strongly after Chelsea scored their goals so they are deserved to be knocked out by Chelsea.
Kai Harvertz is like a player for big match in Champions League. Seasons ago he scored a goal in a final match and brought Chelsea to their second Champions League trophy. In the match with Dortmund, he made some great shots and were too confident on the penalty spot.
Sterling was luckily to have chance to make another shot after he missed a great chance with his first touch. However Dortmund defense system is responsible for the first goal as they gave Sterling too much space and time to handle that situation.
Dortmund are struggling up front because of the lack of specialist long-range executors, this can be seen from the use of set-pieces that don't dare to go straight to goal. For the rhythm of the game, I quite salute the two teams because in the second half everyone played fast and pushed Chelsea to perform more optimally.
With this defeat, a time for Jude Bellingham in Dortmund is counting down and he is closely to his exit gate from BvB stadium. In fact, Jude missed a great chance to score one important goal for Dortmund within the 5m5 area.
