The Belgian duo have both been linked with Stamford Bridge exits this summer with Real Madrid believed to be strongly interested in striking deals.
Hazard – who returned to training yesterday following the World Cup – will not be allowed to leave the Blues this summer with the west London club having refused to indulge in talks.
But they have taken a less strict approach to goalkeeper Courtois’ future with the 26-year-old’s contract at Chelsea running out next summer.
And a deal appears increasingly likely before Thursday’s transfer window deadline with the shot-stopper having failed to report to training alongside Hazard.
Maurizio Sarri had hoped to conduct face-to-face talks on the player’s future but Courtois is still in Belgium as he hopes to force a move to Madrid.
And while Chelsea team-mate Luiz, who has broken back into the first-team picture under Sarri, hopes to see Courtois and Hazard stay at the club – he is confident life will continue beyond one, or both, of them.
“Chelsea wants for the best players to stay,” Luiz said following Chelsea’s Community Shield loss to Manchester City.
“They know Chelsea a lot, so they know what they’ve had here, the fun they’ve had here.
“Everybody loves them and I hope they can stay.
“I want them to stay, because we have top players with the confidence.
“[But] If they decide to leave, I think we will continue with fantastic players.”
Chelsea have made just the two signings so far with Jorginho’s £57million arrival having followed Sarri’s appointment, while the Italian also brought in Rob Green to become their new third-choice keeper.
But their summer has been dominated by the possibility of high-profile outgoings with wide-man Willian another who might have left this summer.
The Brazilian was subject of interest from Manchester United, Barcelona and Real with Chelsea having fended off a number of bids to hold on to the attacker.
And his compatriot Luiz insists an exit was never on the cards.
He revealed: “Since the beginning, he told me he loved Chelsea. To leave Chelsea, would be something totally out of the reality – if he really wanted to leave or if Chelsea really wanted to kick him out.
“This is not the reality. Chelsea loves Willian, Willian loves Chelsea, so that’s great.
“He played on Sunday after coming back after the World Cup, and he has already shown his quality. I wanted him to stay.”
Chelsea conclude their pre-season this evening at Stamford Bridge against Lyon (8.05pm) and start their Premier League campaign away at Huddersfield on Saturday (3pm).
