The Dutchman was speaking after their home defeat to Newcastle United on Monday night, which left Leicester staring down at relegation.
Van Nistelrooy, on his own future, said afterwards: “The most important thing is the club and these players, that’s what I would say for now."
Pressed further, he added: “The most important thing is the club and the players, that is my reaction.”
The former Manchester United striker and assistant coach also stated: “What I want to say is that it’s very disappointing.
"If I speak for myself, coming here with the intent to bring the club forward. So far it didn’t work.
“I tried different things, different players, different structures, without results. That’s what I can say about how I feel at this moment.”
