Ahead of today's clash, 24-year-old Mata has netted four goals in eight Premier League appearances and has provided five assists.
He said: "This is the best form I have ever been in. It's been a very good season for me. October was a good month and I have to keep on improving. Maybe I am because this is my second season in England and I know how the football is.
"I am very happy to play with Oscar and Hazard. They are doing really well. I love the way they play because, more or less, it is my way."
