The Englishman has not always enjoyed his time at the Stamford Bridge club.
But he appears focused and in the best form of his career.
He has three goals and five assists in the past ten games, including one each against Watford in a 3-0 win.
Speaking to reporters after the game, he discussed his form: "We are all humans, we make mistakes and I am no exception.
"But it was not taking any attention away from my football for me. It never did. I am a professional and I always work hard.
"I've been feeling fit and I worked really hard during the lockdown to make sure I was ready. I feel that is paying off now because I feel really fit and really good. I just want to carry this on now. It is great that the goals are going in as well.
"You are always pleased when there is an end product to your play. We have been working on that in training and it is great when it pays off in matches.
"With the players we have like Mason [Mount] and Christian in the team, we are always going to get goals."
