Their relationship soured after Villas-Boas quit his coaching team at Inter Milan to start his own managerial career but Luiz told the London Evening Standard: "It is Tottenham v Chelsea, not Mourinho v Villas-Boas. It will be a fantastic derby. Everyone will want to watch this game, everyone will want to play in this game. It will be fantastic.
"They have a great team, it is always so difficult to play against them and this season is the same.
"We need to play to win because we want to be top of the table."
