The Belgium midfielder was named Barclays Premier League player of the month for November after scoring four goals and being involved in creating two others.
The Toffees are currently fourth in the table, following a 2-1 victory over Spurs at Goodison Park on Sunday.
And the 25-year-old Belgian told the club's website: "Everybody wants to play Champions League next season.
"So we work hard for this and hopefully we can finish in the top four.
"At the moment I am playing well. I am happy - but the most important things are the team and the club.
"I try to give my maximum in every game. The manager likes it when I play in attack. I've been scoring the goals and I work hard on the pitch."
