From all quarter final UEFA Champion League participants only Chelsea drop from top fourth standing position in domestic league, Real Madrid, Manchester City, Bayern Munich and FC Porto on 2nd position each domestic league. For Napoli and Benfica success manage top standing position in their domestic league and left Chelsea have dropped to 10th standing in Primer League.
Seems terrible with their performance between Champion League and Primer League because success qualify to quarter final but have poor performance in domestic league. I don't sure about Chelsea's lucky keep going on at the quarter final round because against Real Madrid are experienced team in Champion League is not easy and have quit well performance in La Liga.
Yes, if you look at his performance in the domestic league, Chelsea seems to be having trouble in the quarter-finals. Real Madrid are the favorites in this tournament and they are quite experienced. Even though these two teams have met each other and produced fairly balanced average results, this season the performances of these two teams are in stark contrast. The Blues this season are in a transitional phase, many things have changed compared to Chelsea's previous face. The presence of a new owner and a new coach made the team's condition fluctuate, which is why they are still struggling in the Premier League to this day.
Meanwhile, Real Madrid, even though they started to slump in La Liga, in the Champions League they showed a different appearance. The current condition of the El Real team has not changed much, 90% of which are still adorned with old faces. With a wealth of experience and also being the defending champion, I'm sure Madrid will easily beat Chelsea, but with a record that the condition of the Madrid players are all in excellent condition.
