Chelsea boss Mauricio Pochettino admits he is baffled by the hometown jeers for Raheem Sterling.
Sterling has been barracked by a section of the Blues support this season.
Pochettino said: "Someone told me that, but I didn't hear it. I've only been here nine months, but I don't understand why this is happening. It's hard to know exactly why.
"He is fully dedicated to Chelsea, he does well and is always very committed.
"He is one of the players who is at 99 percent of the training sessions. Always training, always available. Sometimes he's good, other times not so good - just like everyone else."
