Chelsea manager Maurizio Sarri is satisfied Thibaut Courtois' departure to Real Madrid will not trigger further defections such as the Belgian goalkeeper's compatriot, playmaker Eden Hazard.
Sarri believes Hazard is happy and does not have the same personal reasons as Courtois to move to Madrid -- he wanted to be closer to his two young children who live there with their mother, from whom he is estranged.
Sarri is preparing for his Premier League managerial debut against Huddersfield Town tomorrow and he will be seeking a much-improved performance than the limpid one Chelsea gave in the 2-0 defeat by Manchester City in last Sunday's Community Shield.
"I think it's impossible," he said at his eve of match press conference about the possibility of losing further players to mainland European clubs whose transfer window unlike England's -- which shut on Thursday -- remains open till August 31.
"Here the market is closed, so we cannot change important players now. It's impossible.
"Hazard is with us.
"I think definitely. It's not a problem. I have spoken with him three, four times, for everything.
"He never said something about the market. I think he's very happy to stay here."
