The Germany striker effectively joined Newcastle as a direct replacement for Alexander Isak after his controversial move to Liverpool.
Woltemade told GQ: Of course, I knew that there was something going on about Isak.
“But honestly, in England people just care about English football and in Germany, it is the same.
"So I was not realising that the situation was so hard. But I felt it directly when I came. People were so happy that they got a new striker.
“I went to an away game (Leeds) as a spectator and the fans went crazy! They all ran into me and sang songs about me. Of course, I knew there was pressure because I came for a lot of money. But I liked it.”
Woltemade put through his own net as Newcastle lost the Tyne-Wear derby to Sunderland earlier this season.
He added, "It was a bad, bad feeling.
"I had never scored an own goal before, especially in this game… when I was sitting on the bench, I was like, 'Wow, maybe the fans will destroy me'. But when I came into the dressing room, I put up my phone and I just saw good messages.
“This helped me a lot, because of course I understand it was the most important game. I was so thankful. It showed me I’m in the right place.”
