After sealing their place in the Europa League final against Benfica on May 15, last season's Champions League winners first turn their attentions to the battle for the Barclays Premier League top four with games against champions Manchester
United on Sunday and Tottenham on Wednesday.
"All season we've tried our best, but now the team has more confidence to play together and in the philosophy of Rafa Benitez," Luiz told Chelsea TV.
"Everyone wants to play in the Champions League next year, everyone wants to win one title this season.
"We need to show the character, to show our best and to win the [Europa League] title."
