Chelsea manager, Thomas Tuchel, has said he took off Cesar Azpilicueta, Christian Pulisic and Timo Werner during their 1-1 draw with Real Madrid, because they were struggling with tiredness.
Pulisic opened the scoring in the 14th minute of Tuesday’s Champions League semi-final first leg.
Werner had earlier missed a golden chance to break the deadlock, firing a close-range strike straight at Thibaut Courtois.
The Blues were soon made to pay for their profligacy, after Karim Benzema equalised on the half-hour mark.
Reece James, Hakim Ziyech and Kai Havertz were brought on in place of Azpilicueta, Pulisic and Werner with 20 minutes left.
When asked whether it was always his plan to make changes just past the hour-mark, Tuchel replied: “No, you cannot plan. But in this moment we lost too many balls, we had too many technical errors.
“Azpi looked very tired, Christian looked very tired, same for Timo.
“We worked very hard last week so no, we decide from what we see and what is necessary in the game.”
