The Denmark has struggled for regular action at Spurs this season.
"I'm obviously not happy with what's going on at the club. It's nothing that's secret, but it's also not something I need to argue about," he told Bold.
"I can put my head on the pillow at night and know that I will give what I need to convince the coach. That is not the case at the moment, and the coach (Ange Postecoglou) must explain why. But I know I can contribute to the team at Tottenham, and I have to go home and show it again.
"I am motivated to finish the season properly and for Tottenham to finish properly, but what is going on is of course not satisfactory."
