The 27-year-old won a first FA Cup with the Blues on Saturday, scoring the decisive penalty in the 1-0 win over Manchester United.
"We have a lot of top players, players who are used to winning trophies. We will be ready next season," Hazard said in the London Evening Standard.
"I think all of the players and the club want one thing and that's to win the title.
"Of course we will see if we can bring in some new players. But we will be focused on winning the title."
