"Sometimes it doesn't help when the fans are not happy," said the midfielder. "When you give the ball away there is pressure. This is our job.
"Fans come to watch the football and we have a responsibility to pay them back and make sure we play well. Every game we try to do that, sometimes it works, sometimes it doesn't.
"I have been here for seven years and they (the fans) are fantastic and have always supported us until the end. I hope that continues throughout the season.
"This is when we need them the most. Let's hope we can all go through the rest of the season together. Chelsea fans have always been great and I know they will continue to be great with the players."
