The Blues boss reiterated that neither of the two players were used in negotiations to sign Wayne Rooney, insisting he has no intention to let either leave Stamford BridgeChelsea boss Jose Mourinho has insisted there is "no chance" the club will sell Juan Mata or David Luiz this summer.
The duo's future at Stamford Bridge was recently cast into doubt after they were rumoured to have been offered as part of a deal for Manchester United striker Wayne Rooney, a claim the west London club strenuously denied.
The Portuguese boss was quick to address the issue in his first press conference after arriving in Malaysia as part of the pre-season tour, responding definitively to questions as to whether he would consider selling either player.
"No chance. No chance," he told reporters, before responding to whether the pair would still be at the club next season by insisting: "Yes. For me that's enough."
The former Real Madrid boss also took the opportunity to remind international players that they cannot afford to sit on the bench this season if they are hoping to secure a place in next summer's World Cup, perhaps a subtle reminder to transfer target Wayne Rooney.
"I always say to my players that when they are with the national team they don't think about our club, but when they are with the club they have to forget the national team and give everything to the club," he explained.
"At the same time, normally players who want to go to their national team and play for their country, normally they must be first choice players for their clubs and be playing regularly. That's the big motivation if you are thinking about playing at the World Cup.
"If they want to go to the World Cup and they're second choice at their club, then they're in trouble, they're in trouble.
"I think it's a crucial year for them. Many national team coaches are worried because they want players to play regularly for their clubs. They have to play for me to play for them. It's a combination. They must share the situation."
Rooney made just 36 appearances for Manchester United after falling behind Robin Van Persie in the pecking order last season - his lowest tally since moving to Old Trafford in 2004.
