Good performance from the home team Chelsea they were so brilliant in the last 20 minutes before the half time and they got rewarded with a goal from Raheem Sterling in the 43 minutes to end the halftime.
Chelsea have been the better side in the first half and they need one more goal to move to the next round of the competition.
Chelsea seems like learning much after their first defeat against Dortmund in the first leg. Now, their performance is getting much better and better in every line. It proves the progress and Chelsea now is leading with a score 2 - 0 against Dortmund until the 58 minutes. These leading scores make Chelsea is also leading in the aggregate. But we still cannot guarantee or predict whether Chelsea will exactly win the match or not, or whether there will be acounterattackk from Dortmund or not because there are still many times remaining. Aside from the result, we can see there is good progress by Chelsea so far during this match and they are also dominating the match very well.
