Chelsea boss Jose Mourinho was pleased with Kenedy's showing in a losing debut to Crystal Palace.
Mourinho felt the young Brazilian lifted the team when he was thrown on.
"Cesar Azpilicueta was fantastic but I took him off because I wanted to give more depth to the side and to play without a left-back and with a kid going forward like Kenedy did," said Mou.
"He is a good personality and this is what we needed at the time. Kenedy was responsible for an improvement in the team."
