Chelsea midfielder Cole Palmer admits they need to improve after yesterday's 2-2 draw with Arsenal.
Palmer converted a penalty before Chelsea blew a 2-0 lead as the Gunners fought back for the point.
He later said: "We are obviously very disappointed not to get the three points, but Arsenal are a very good team, one of the best in the league.
"We came face to face with them.
"There are still many areas in which we can become stronger. We are moving in the right direction, this is not the end."
