Chelsea defender David Luiz says the players are determined to stay in touch with the title race leading into the Christmas schedule.
The Blues are currently third following their goalless draw with Everton.
Luiz told chelseafc.com: "The marking from Everton was amazing. They blocked the space in the middle so we didn't have a lot of combinations in the middle and from the sides, and in the end they were a bit lucky because we tried to score but didn't score.
"We did everything to try to win. Sometimes it's possible, sometimes it's not, and we're still there, trying to be at the top of the table so we're going to fight until the end.
"Most of the teams now come here with two lines and trying to lock us up so it's up to us to find the way to score."
