Tottenham made an attempt for Ings this week.
But Hasenhuttl said: “I don't know how often I spoke last season about Danny Ings and how important he is for our club.
“The only thing I want to say for these rumours is there is absolutely zero interest from Danny to go anywhere.
“He is 100 per cent happy to be here. For us it is 100 per cent not discussable that we leave (let go) one of the best players in Europe.
“Any rumours about that are absolutely nonsense and hopefully this is the last time we speak about this.
“He's the most important striker in our team, one of our own, if you want.
“He loves what we do here. He loves to play for us and the team loves to play with him."
