And although Chelsea would like to retain the services of the 26-year-old and risk losing him for free next summer, keeping an unsettled player could adversely affect the dressing room atmosphere.
Last week, Courtois was pushed by the Belgian media about his future, and the player refused to give any indication as to where he will be playing in 2018/19.
Chelsea goalkeeper Thibaut Courtois, who has been linked with a move to Real Madrid, did not report for training with the Premier League club on Monday. "For him this is a big decision because he wants to be near his family, and there is an offer in place for Chelsea to accept". "But my head is here in the club".
Courtois missed Chelsea's 2-0 defeat against Manchester City in the Community Shield on Sunday while he continues to rest after the World Cup.
It is claimed that Maurizio Sarri would look to replace Thibaut Courtois at Chelsea with Milan's Pepe Reina.
This will be his sixth year with the west London side.
"I hope he's not the same as Conte!" he told ESPN Brasil. The other clubs that compete with us are really strong and already have fantastic teams and squads, like Chelsea, Tottenham, Manchester City, or they are investing massively like, for example, Liverpool, that is buying everything and everybody.
During this afternoon's recovery training session, Courtois was noticeably absent, leading many media outlets to say he has gone "AWOL" as he tries to force a move to Real Madrid.
"I want them to stay, because we have top players with the confidence", Luiz said.
"I don't think I should comment too much about that in this moment because we are at a delicate time in the process".
