Maurizio Sarri has admitted he was concerned Eden Hazard might leave Chelsea this summer after rumours linked the 27-year-old with a move to Real Madrid.
“Chelsea are one of the most important clubs in Europe,” Sarri said.
“I think one of the most important clubs in Europe cannot sell an important player without the possibility of buying a player on the same level.
“Of course when I joined, I was concerned about this problem. But the first time I spoke to him, I was sure that he would stay.”
